    1. Inside Cover: Dodecanuclear-Ellipse and Decanuclear-Wheel Nickel(II) Thiolato Clusters with Efficient Femtosecond Nonlinear Absorption (Angew. Chem. Int. Ed. 25/2010) (page 4146)

      Chi Zhang, Tsuyoshi Matsumoto, Marek Samoc, Simon Petrie, Suci Meng, T. Christopher Corkery, Robert Stranger, Jinfang Zhang, Mark G. Humphrey and Kazuyuki Tatsumi

      Article first published online: 30 APR 2010 | DOI: 10.1002/anie.201002348

      Thumbnail image of graphical abstract

      A geometrically unprecedented dodecanuclear nickel(II) elliptical cluster and two decanuclear nickel(II) wheel clusters have been obtained by stepwise introduction of different thiolates at a nickel(II) center, as described by C. Zhang, M. G. Humphrey, K. Tatsumi et al. in their Communication on page 4209 ff. The novel toroidal molecular configurations and strong wavelength-dependent nonlinear optical behavior in these “tiara-like” chromophores have been shown by theoretical studies to be driven by Ni–S π-bonding interactions.

      Reaction-Diffusion Systems in Intracellular Molecular Transport and Control (pages 4170–4198)

      Siowling Soh, Marta Byrska, Kristiana Kandere-Grzybowska and Bartosz A. Grzybowski

      Article first published online: 1 JUN 2010 | DOI: 10.1002/anie.200905513

      Thumbnail image of graphical abstract

      Both prokaryotic and eukaryotic cells couple chemical reactions with diffusion (in reaction-diffusion or RD systems) to achieve spatially and temporally coordinated delivery of the molecules to intracellular reaction sites. These cellular RD systems are based on several common architectures and motifs that enable cells to build, operate, and position structures for cell division, gradient sensing, signal transduction and amplification, and cell motility.

    1. Ionothermal Synthesis

      Layered Zinc Phosphates with Photoluminescence and Photochromism: Chemistry in Deep Eutectic Solvents (pages 4200–4204)

      Pei-Ci Jhang, Niang-Tsu Chuang and Sue-Lein Wang

      Article first published online: 20 APR 2010 | DOI: 10.1002/anie.201001145

      Thumbnail image of graphical abstract

      A metal-activator-free orange phosphor was synthesized from ZnO/H3PO3/diamine in choline chloride/oxalic acid deep eutectic solvent, which also acted as methylating agent and source of ethylene glycol (EG) by dissociation of choline ions. Interlayer incorporation of a dimethylated amine made the resulting layered zinc phosphate (“ZnPO”, see picture) photochromic, and their interaction with EG formed fluorophores with orange photoluminescence.

    2. Self-Assembled Nanotubes

      Metal–Organic Calixarene Nanotubes (pages 4205–4208)

      Stuart Kennedy, Georgios Karotsis, Christine M. Beavers, Simon J. Teat, Euan K. Brechin and Scott J. Dalgarno

      Article first published online: 5 MAY 2010 | DOI: 10.1002/anie.201001078

      Thumbnail image of graphical abstract

      Control over molecule conformation and transition metal cluster formation has been combined to afford metal–organic calixarene building blocks that induce nanotube formation in the solid state. The resulting assembly type can have chosen magnetic properties, and has three types of solvent filled channel that differ in diameter and shape (see picture).

    3. Tiara Structures

      Dodecanuclear-Ellipse and Decanuclear-Wheel Nickel(II) Thiolato Clusters with Efficient Femtosecond Nonlinear Absorption (pages 4209–4212)

      Chi Zhang, Tsuyoshi Matsumoto, Marek Samoc, Simon Petrie, Suci Meng, T. Christopher Corkery, Robert Stranger, Jinfang Zhang, Mark G. Humphrey and Kazuyuki Tatsumi

      Article first published online: 26 APR 2010 | DOI: 10.1002/anie.200907074

      Thumbnail image of graphical abstract

      Crowned with success: Stepwise coordination of two kinds of thiolate ligands to a nickel(II) center affords a dodecanuclear ellipse (see structure) and two decanuclear wheel-like NiII–thiolato clusters. The wavelength-dependent nonlinear optical behavior of these tiara-like compounds was investigated and supported by theoretical studies. The results suggest that Ni[BOND]S π bonds play a crucial role.

    4. Organic Materials

      Synthesis of Functionalizable Boron-Containing π-Electron Materials that Incorporate Formally Aromatic Fused Borepin Rings (pages 4213–4217)

      Anthony Caruso Jr., Maxime A. Siegler and John D. Tovar

      Article first published online: 7 MAY 2010 | DOI: 10.1002/anie.201000411

      Thumbnail image of graphical abstract

      Not a natty B[BOND]OH: Borepin-based extended π-electron molecules contain bulky substituents that shield the vacant boron p orbitals and allow synthetic manipulation and purification under ambient conditions. These borepin-containing compounds (see picture; Mes*=1,3,5-tris(tert-butyl)phenyl; B orange, C gray) display reversible cathodic electrochemistry and can be viewed as n-type analogues to bent acene hydrocarbons.

    5. Self-Assembly

      Supramolecular Hydrogels and High-Aspect-Ratio Nanofibers through Charge-Transfer-Induced Alternate Coassembly (pages 4218–4222)

      K. Venkata Rao, K. Jayaramulu, Tapas Kumar Maji and Subi J. George

      Article first published online: 30 APR 2010 | DOI: 10.1002/anie.201000527

      Thumbnail image of graphical abstract

      Gelling together: The alternate coassembly of a noncovalent donor–acceptor (D–A) amphiphilic pair in water results in very long nanofibers that form hydrogels (see scheme). Microscopic and single-crystal studies have provided an insight into the hierarchical self-assembly of the charge-transfer (CT) amphiphile, which consists of coronene and a viologen derivative, into cylindrical micelles and gels as the concentration of the D–A pair is increased.

    6. Microspheres

      Amphiphilic Hollow Carbonaceous Microspheres with Permeable Shells (pages 4223–4227)

      Dezhi Ni, Lei Wang, Yunhui Sun, Zhengrong Guan, Sen Yang and Kebin Zhou

      Article first published online: 30 APR 2010 | DOI: 10.1002/anie.201000697

      Thumbnail image of graphical abstract

      An inside job: Porous hollow carbonaceous microspheres can be easily fabricated by hydrothermal treatment of Saccharomyces cerevisiae cells. An amphiphilic surface and porous shell structure endow these microspheres with phase-transfer features and the ability to enrich proteins inside their hollow interiors. These characteristics will enable their application in drug delivery, active ingredients encapsulation, adsorption, and separation techniques.

    7. Macrocyclic Ligands

      Striking Inflammation from Both Sides: Manganese(II) Pentaazamacrocyclic SOD Mimics Act Also as Nitric Oxide Dismutases: A Single-Cell Study (pages 4228–4232)

      Article first published online: 5 MAY 2010 | DOI: 10.1002/anie.200905936

      Thumbnail image of graphical abstract

      Removing cytotoxics: A MnII–pentaazamacrocycle removes NO., O2.−, and their ONOO product as shown by real-time amperometry at single cells (see picture). This is the first compound able to completely abolish the cytotoxic effects of reactive oxygen (ROS) and reactive nitrogen species (RNS) in inflammation.

    8. Photosystem II

      Location of Potential Substrate Water Binding Sites in the Water Oxidizing Complex of Photosystem II (pages 4233–4236)

      Article first published online: 5 MAY 2010 | DOI: 10.1002/anie.200906253

      Thumbnail image of graphical abstract

      Water divining: DFT calculations are applied to a set of Mn4Ca cluster models of the water oxidizing complex (WOC) in photosystem II (see picture; O red, H white, Ca light gray, Mn dark gray, C black). The calculations uncover a model of the active site which rationalizes recent experimental data probing substrate interaction with the WOC and identifies the most likely substrate water binding sites.

    9. Analytical Methods

      Determination of Arsenic Poisoning and Metabolism in Hair by Synchrotron Radiation: The Case of Phar Lap (pages 4237–4240)

      Ivan M. Kempson and Dermot A. Henry

      Article first published online: 29 APR 2010 | DOI: 10.1002/anie.200906594

      Thumbnail image of graphical abstract

      Fresh physical evidence about the demise of the racehorse Phar Lap (see photograph) has been gathered from the study of mane hair samples by synchrotron radiation analysis with high resolution X-ray fluorescence (XRF) and X-ray absorption near edge structure (XANES) analyses. The results are indicative of arsenic ingestion and metabolism, and show that the racing champion died from arsenic poisoning.

    10. Mesoporous Materials

      Self-Repair of a One-Dimensional Molecular Assembly in Mesoporous Silica by a Nanoscopic Template Effect (pages 4241–4245)

      Hendrik O. Lintang, Kazushi Kinbara, Kenichi Tanaka, Takashi Yamashita and Takuzo Aida

      Article first published online: 10 MAY 2010 | DOI: 10.1002/anie.200906578

      Thumbnail image of graphical abstract

      Upon confinement of a trinuclear gold(I) pyrazolate complex in a hexagonal silicate channel, the luminescence center formed by a AuI–AuI metallophilic interaction is not only protected against thermal disruption but also strongly encouraged to self-recover from a heat-induced structural damage. This nanoscopic template effect is negligible for a lamellar silica framework.

    11. Cellular Sensing

      A Nanogel for Ratiometric Fluorescent Sensing of Intracellular pH Values (pages 4246–4249)

      Hong-shang Peng, Judith A. Stolwijk, Li-Ning Sun, Joachim Wegener and Otto S. Wolfbeis

      Article first published online: 5 MAY 2010 | DOI: 10.1002/anie.200906926

      Thumbnail image of graphical abstract

      A ratiometric fluorescent nanogel can sense pH over a range that is applicable to physiological studies. It can be easily prepared and made pH-responsive by addition of a pH probe and a FRET system that utilizes the gel to hold dyes in close proximity (see picture; overlay of coumarin dye and Nile Red fluorescence in kidney cells).

    12. Single Polymers

      Large Mechanical Response of Single Dendronized Polymers Induced by Ionic Strength (pages 4250–4253)

      Ionel Popa, Baozhong Zhang, Plinio Maroni, A. Dieter Schlüter and Michal Borkovec

      Article first published online: 30 APR 2010 | DOI: 10.1002/anie.201001032

      Thumbnail image of graphical abstract

      The mechanical properties of single cationic dendronized polymers can be strongly modified in aqueous solutions by the ionic strength. Given the possibility to tune the elasticity of dendronized polymers significantly through the solvent properties, such polymers may become ideal building blocks for single-molecule machines, especially as actuators or motors.

    13. Mixed-Valence Compounds

      [Na7UIVO2(UVO)2(UV/VIO2)2Si4O16]: A Mixed-Valence Uranium Silicate (pages 4254–4256)

      Cheng-Shiuan Lee, Chia-Hui Lin, Sue-Lein Wang and Kwang-Hwa Lii

      Article first published online: 7 MAY 2010 | DOI: 10.1002/anie.201001095

      Thumbnail image of graphical abstract

      For U′r eyes only: A mixed-valence uranium silicate containing three different valence states of uranium has been synthesized under high-temperature, high-pressure hydrothermal conditions. The structure contains uranium silicate sheets with uranophane anion topology that are connected by UO6 octahedra to form a 2D layered structure with Na+ ions within and between the layers.

    14. Micelles

      Self-Assembly of Thermally Responsive Amphiphilic Diblock Copolypeptides into Spherical Micellar Nanoparticles (pages 4257–4260)

      Wookhyun Kim, Julie Thévenot, Emmanuel Ibarboure, Sébastien Lecommandoux and Elliot L. Chaikof

      Article first published online: 5 MAY 2010 | DOI: 10.1002/anie.201001356

      Thumbnail image of graphical abstract

      Stable micellar structures were synthesized containing cysteine residues at the diblock interface to stabilize micellar structure (see picture). Self-assembly of these copolypeptides affords a new class of protein nanoparticles with potential applications in drug-delivery and bioimaging.

    15. Natural Product Synthesis

      Total Synthesis of (−)-Dactylolide (pages 4261–4263)

      Sang Young Yun, Eric C. Hansen, Ivan Volchkov, Eun Jin Cho, Wai Yip Lo and Daesung Lee

      Article first published online: 10 MAY 2010 | DOI: 10.1002/anie.201001681

      Thumbnail image of graphical abstract

      Multiple metals in action: Relying on the prowess of various metal-catalyzed C[BOND]O and C[BOND]C bond-forming reactions, a concise asymmetric total synthesis of (−)-dactylolide has been achieved (see scheme). The formation of a Z-trisubstituted vinylboronate through an Alder–ene reaction and subsequent rhenium-mediated regioselective transposition of an allylic alcohol are the key features of this convergent synthesis.

    16. Asymmetric Synthesis

      Asymmetric Synthesis of Allylsilanes by the Borylation of Lithiated Carbamates: Formal Total Synthesis of (−)-Decarestrictine D (pages 4264–4268)

      Michael Binanzer, Guang Yu Fang and Varinder K. Aggarwal

      Article first published online: 5 MAY 2010 | DOI: 10.1002/anie.201001223

      Thumbnail image of graphical abstract

      The flip side: (−)-Sparteine-complexed lithiated carbamates react with β-silylvinylboranes with inversion of configuration, whereas the diamine-free lithiated carbamates react with retention of configuration, thereby providing enantio-complementary routes to β-hydroxy allylsilanes (see scheme). The methodology has been applied in a concise formal total synthesis of (−)-decarestrictine D.

    17. Cyclization Reactions

      Gold-Catalyzed Tandem Cyclization of Dienol Silyl Ethers for the Preparation of Bicyclo[4.3.0]nonane Derivatives (pages 4269–4272)

      Hiroyuki Kusama, Yusuke Karibe, Yuji Onizawa and Nobuharu Iwasawa

      Article first published online: 5 MAY 2010 | DOI: 10.1002/anie.201001061

      Thumbnail image of graphical abstract

      Tandem bicycle: A gold-catalyzed geminal carbo-functionalization reaction of 3-siloxy-1,3-dien-8-ynes proceeded smoothly to give bicyclo[4.3.0]nonanes stereoselectively through ring expansion of the bicyclic carbene complex intermediates. The product configuration was different from that of the thermal Diels–Alder adduct.

    18. Supramolecular Catalysis

      Supramolecular Catalysis in the Organic Solid State through Dry Grinding (pages 4273–4277)

      Anatoliy N. Sokolov, Dejan-Krešimir Bučar, Jonas Baltrusaitis, Sean X. Gu and Leonard R. MacGillivray

      Article first published online: 5 MAY 2010 | DOI: 10.1002/anie.201000874

      Thumbnail image of graphical abstract

      Chemical mechanics: Hydrogen-bond-driven self-assembly and mechanochemistry are used to facilitate supramolecular catalysis in the solid state. Mortar-and-pestle grinding proves to be an efficient means to achieve co-crystal formation and turnover using a physical mixture composed of an olefin and catalytic amounts of a ditopic template (see scheme).

    19. Heterocyclization

      Osmium-Catalyzed 7-endo Heterocyclization of Aromatic Alkynols into Benzoxepines (pages 4278–4281)

      Alejandro Varela-Fernández, Cristina García-Yebra, Jesús A. Varela, Miguel A. Esteruelas and Carlos Saá

      Article first published online: 6 MAY 2010 | DOI: 10.1002/anie.201000455

      Thumbnail image of graphical abstract

      The wizard of Os: Regioselective osmium-catalyzed 7-endo heterocyclization of aromatic alkynols affords benzoxepines in good yields. The proposed catalytic cycle involves the key formation of osmium–vinylidene complexes via an alkynyl-hydride–osmium(IV) complex from the starting alkynol.

    20. Hollow Structures

      Synthesis of Cu2O Nanoframes and Nanocages by Selective Oxidative Etching at Room Temperature (pages 4282–4285)

      Yongming Sui, Wuyou Fu, Yi Zeng, Haibin Yang, Yanyan Zhang, Hui Chen, Yixing Li, Minghui Li and Guangtian Zou

      Article first published online: 5 MAY 2010 | DOI: 10.1002/anie.200907117

      Thumbnail image of graphical abstract

      Hollow Cu2O nanostructures with uniform size (see SEM and TEM images) were obtained by oxidative etching of truncated octahedral particle precursors. A unique feature of the as-synthesized nanoframes is that the six {100} faces are absent, and thus they are constructed of eight hexagonal {111} faces, which are expected to be more catalytically active.

    21. Carbenes

      Trapping a Difluorocarbene–Platinum Fragment by Base Coordination (pages 4286–4289)

      Sonia Martínez-Salvador, Babil Menjón, Juan Forniés, Antonio Martín and Isabel Usón

      Article first published online: 6 MAY 2010 | DOI: 10.1002/anie.200907031

      Thumbnail image of graphical abstract

      Caught in the act: Evidence for the intermediacy of difluorocarbene–platinum species along the acidic degradation of Pt[BOND]CF3 bonds was gained by trapping a base-stabilized Pt[DOUBLE BOND]CF2 moiety (see scheme). Attack of an N nucleophile (py*) to the highly electrophilic and extremely reactive difluorocarbene carbon atom takes place with C[BOND]N bond formation.

    22. Asymmetric Synthesis

      Highly Enantioselective Conjugate Addition of Thioglycolate to Chalcones Catalyzed by Lanthanum: Low Catalyst Loading and Remarkable Chiral Amplification (pages 4290–4293)

      Yonghai Hui, Jun Jiang, Wentao Wang, Weiliang Chen, Yunfei Cai, Lili Lin, Xiaohua Liu and Xiaoming Feng

      Article first published online: 6 MAY 2010 | DOI: 10.1002/anie.201000105

      Thumbnail image of graphical abstract

      Ramping it up: The titled reaction has been developed using a chiral N,N′-dioxide–LaIII complex as the catalyst. The reaction proceeded with high yield and enantioselectivity. Remarkably, a high asymmetric amplification was observed, as 98 % ee was achieved using 1 mol % L/La(OTf)3 in which the ee value of L was 2 % ee. Tf=trifluoromethanesulfonyl.

      Make it strained and fluorinated! A rhodium-catalyzed domino diazotization/cyclopropenation reaction involving trifluoroethylamine hydrochloride and alkynes has been developed for the synthesis of trifluoromethyl cyclopropenes that can be easily functionalized to afford useful CF3-containing building blocks for drug discovery.

      Who eight all the πs? Hexaphyrin(1.1.1.1.1.1) rearranges into figure-of-eight hexaphyrin(2.1.1.0.1.1) upon BIII complexation (see scheme). Redox reactions convert between 30π and 28π electron systems requiring the BIII coordination to change between trigonal and tetrahedral. Removal of the BIII centers allows hexaphyrin(2.1.1.0.1.1) to complex two PdII centers.

      Under an extreme pressure of 12 GPa, mesoporous coesite can be formed directly from periodic mesoporous silica without the aid of a template. The porous coesite particles obtained from SBA-16 are single crystalline, with a pore size of about 4 nm and about 50 % porosity. The formation can be attributed to the kinetically controlled crystallization of a nonporous elastically strained glasslike silica intermediate (see scheme).

      Linear Semicrystalline Polyesters from Fatty Acids by Complete Feedstock Molecule Utilization (pages 4306–4308)

      Dorothee Quinzler and Stefan Mecking

      Article first published online: 7 MAY 2010 | DOI: 10.1002/anie.201001510

      Thumbnail image of graphical abstract

      Complete and linear incorporation of fatty acids into polyesters is achieved by isomerizing carbonylation to give polymerization-quality diesters and their polycondensation with the corresponding diols obtained by reduction. The strictly linear and long-chain hydrocarbon nature of these polyesters results in a high degree of crystallinity and melting behavior akin to common thermoplastics.
