      Article first published online: 10 OCT 2006 | DOI: 10.1002/anie.200690137

      A new melt approach has enabled the synthesis of the first catena-hexaphosphorus dications, as described in the Communication by N. Burford, J. J. Weigand, and co-workers on page 6733 ff. The cover picture (by Jared MacPherson) shows a photograph of the reaction melt of 4/5 (PhP)5, 2 Ph2PCl, and 2 GaCl3 at 100 °C, which solidifies to yield [P6Ph8][GaCl4]2 quantitatively upon further heating. Such cations represent a new direction in phosphorus chemistry and promise a parallel to catena-carbon (organic) chemistry.

    1. Mechanistic Questions about the Reaction of Molecular Oxygen with Palladium in Oxidase Catalysis (pages 6612–6615)

      Keith M. Gligorich and Matthew S. Sigman

      Article first published online: 20 SEP 2006 | DOI: 10.1002/anie.200602138

      Thumbnail image of graphical abstract

      Which pathway? Aerobic Pd-catalyzed oxidation reactions couple organic-substrate oxidation to the reduction of O2. Two pathways are prevalent for the regeneration of the active PdII catalyst (see scheme; SubH2= substrate; SubOx=oxidized substrate), and recent studies have provided a deeper fundamental understanding of the interactions of Pd with O2.

    2. Cyclobutadiene: The Antiaromatic Paradigm? (pages 6616–6619)

      Thomas Bally

      Article first published online: 20 SEP 2006 | DOI: 10.1002/anie.200602279

      Thumbnail image of graphical abstract

      The heat of formation of cyclobutadiene has recently been determined by Kass and co-workers. This determination is taken as an occasion to reflect on the difficulty to extract from this number the “antiaromatic destabilization” and the strain energy of this most fundamental species.

    1. Application of Solvent-Directed Assembly of Block Copolymers to the Synthesis of Nanostructured Materials with Low Dielectric Constants (pages 6648–6652)

      Thomas M. Hermans, Jeongsoo Choi, Bas G. G. Lohmeijer, Geraud Dubois, Russell C. Pratt, Ho-Cheol Kim, Robert M. Waymouth and James L. Hedrick

      Article first published online: 14 AUG 2006 | DOI: 10.1002/anie.200601888

      Thumbnail image of graphical abstract

      An inverse relationship: Mixtures of poly(dimethylacrylamide)-block-polylactide copolymer (PDMA-b-PLA) with organosilicate oligomers (PMSSQ) selectively sequestered into the PDMA phase form micelles and inverse micelles in solution depending on the solvent. The micellar structures are imprinted into the resulting cured organosilicate to give monoliths or assemblies of densely packed organosilicate nanoparticles, respectively.

    2. Isolation of Cyclopropenylidene–Lithium Adducts: The Weiss–Yoshida Reagent (pages 6652–6655)

      Vincent Lavallo, Yutaka Ishida, Bruno Donnadieu and Guy Bertrand

      Article first published online: 20 SEP 2006 | DOI: 10.1002/anie.200602701

      Thumbnail image of graphical abstract

      Luck is important: In the 1970s, Yoshida and Weiss both had the right cyclopropenium cation precursor. With the right counteranion, they would have isolated the first carbene–lithium adduct (see scheme; C black, N blue, O red, Li pink, B yellow, F green). With the right base and counteranion combination, they would have isolated the first stable free carbene.

    3. Role of Rotational Alignment in Dissociative Chemisorption and Oxidation: O2 on Bare and CO-Precovered Pd(100) (pages 6655–6658)

      Andrea Gerbi, Letizia Savio, Luca Vattuone, Fernando Pirani, David Cappelletti and Mario Rocca

      Article first published online: 20 SEP 2006 | DOI: 10.1002/anie.200602180

      Thumbnail image of graphical abstract

      It's all in the spin: The initial sticking probability of O2 on a CO-precovered Pd(100) surface and the rate of CO2 production are strongly affected by the alignment of the incoming molecules. Whereas O2 molecules impinging with cartwheel-like motion can stick in small holes, molecules moving with helicopter-like motion need a large array of free sites (see picture).

    4. Interfacing Electrocatalysis and Biocatalysis with Tungsten Carbide: A High-Performance, Noble-Metal-Free Microbial Fuel Cell (pages 6658–6661)

      Economic power: A robust and low-cost microbial fuel cell has a tungsten carbide anode electrocatalyst, a pyrolyzed iron(III) phthalocyanine cathode catalyst for oxygen reduction, and hydrogen-producing soil bacteria as biocatalysts (see picture). Power and current densities of up to 585 μW cm−2 and 3 mA cm−2, respectively, are achieved.

    5. New Methods for Anion Recognition and Signaling Using Nanoscopic Gatelike Scaffoldings (pages 6661–6664)

      Rosa Casasús, Elena Aznar, M. Dolores Marcos, Ramón Martínez-Máñez, Félix Sancenón, Juan Soto and Pedro Amorós

      Article first published online: 20 SEP 2006 | DOI: 10.1002/anie.200602045

      Thumbnail image of graphical abstract

      Colorimetric guest signaling is effected by a supramolecular approach that uses a mesoporous hybrid solid functionalized with gatelike scaffoldings. When the gate is open, a dye (see scheme; orange dots) embedded in the pore walls of a mesoporous solid is released into the solution giving color. If the appropriate anion (red dots) is present the gate is closed, the dye is locked into the pores, and the solution remains colorless.

      Molecules in suits: Supramolecular assistance leads to the self-assembly of a mechanically interlocked compound called a suit[2]ane (see picture). Two bisformyldipyrido[24]crown-8 rings (red) recognize and encircle two secondary ammonium ion centers on a rigid linear scaffold (blue for the most part in the picture) with a bulky midriff, followed by the dynamic formation of four imine bonds involving two p-phenylenediamine molecules as linkers.

    7. Evolution of Polyoxoniobate Cluster Anions (pages 6670–6672)

      Article first published online: 20 SEP 2006 | DOI: 10.1002/anie.200602200

      Thumbnail image of graphical abstract

      A new geometry for polyoxoniobates is observed in {Nb24O72H9}15−, the largest isopolyoxoniobate cluster anion known to date. Its structural evolution from isolated Lindqvist anions [Nb6O19]8− and the cyclic pyrochlore unit [Nb6O30] through to the complex dimer [({Nb24O72H9} {Cu(en)2(H2O)}2{Cu(en)2})2]18− is discussed.

    8. Double-Faced Micelles from Water-Soluble Polymers (pages 6673–6676)

      Thumbnail image of graphical abstract

      Asymmetric disk-shaped Janus micelles form spontaneously and reversibly when simple water-soluble diblock copolymers in aqueous solutions are mixed. The combination of associative and segregative phase separation within one nanostructure results in a disk-shaped micelle with a complex coacervate core and an asymmetric water-swollen corona which is microphase-separated into two distinct domains or faces.

      The risk assessment of carbon materials, an important topic in nanomaterials research, has been hampered by the lack of characterizable samples. Transition-metal-free carbon nanohorn aggregates have been prepared that are covalently bonded aggregates of single-walled nanotubes. They were functionalized to give water-soluble derivatives (see picture), which were incubated with cells in cytotoxicity assessments.

      A mixed-valent subnitride host structure with parallel channels (equation imageequation imageequation image) readily accommodates metal guest chains (see picture; Ca2+ orange, Ca1.5+ red, N green, M black). These incommensurate guests, which comprise linear chains of equidistant metal atoms (M=Ag, Ga) or fragments thereof (M=In, Tl), interact only weakly with their hosts.

      The carbon–phosphorus–antimony cage of P2C2tBu2SbCl (see picture) adopts an envelope-type structure which is quite distinct from its phosphorus analogue, the tricyclic compound P2C2tBu2PCl. DFT calculations reveal that subtle changes in electronic structure as a result of the inert-pair effect lead to profound differences in structural and dynamic behavior.

      A tweak here, a tweak there: A series of analogues of glucosamine-6-phosphate (GlcN6P, see picture) was used to examine the molecular-recognition characteristics of a glmS ribozyme that is activated by this ligand. Although several functional groups on the ligand are critical for binding, there are opportunities to create new analogues that fully trigger ribozyme action.

      Thumbnail image of graphical abstract

      Shear innovation: By analyzing the crystallographic shear (CS) structures of “Pb2Fe2O5” (see picture; spheres Pb, polyhedra FeO6/FeO5), new building principles are derived for perovskite-based compounds containing cations with a lone electron pair in the A sites of the perovskite structure. The chemical composition can be adjusted by varying the orientation of the CS planes and the thickness of the perovskite slabs between the planes.

      No coking: A Pt/WO3/Al-ZrOx nanocomposite enables the efficient conversion of various hydrocarbons at a temperature as low as 150 °C (see figure, X=conversion) without deep cracking or coking problems. This novel catalyst might potentially be used for the production of high-octane fuel with a low content of aromatics by converting n-alkanes into their multibranched isomers with excellent selectivity.

      Ring round: 1-Acyl-1-alkynyl-cyclopropanes smoothly react with nucleophiles in the presence of a gold(I) catalyst to afford substituted furans in a fully atom-economical fashion (see scheme; Nu=nucleophile, Tf=trifluoromethanesulfonyl). The reaction tolerates a wide range of substrates.

    17. A Square-Planar Organoiron(III) Compound with a Spin-Admixed State (pages 6707–6711)

      Pablo J. Alonso, Ana B. Arauzo, Juan Forniés, M. Angeles García-Monforte, Antonio Martín, Jesús I. Martínez, Babil Menjón, Conrado Rillo and José J. Sáiz-Garitaonandia

      Article first published online: 15 SEP 2006 | DOI: 10.1002/anie.200601774

      Thumbnail image of graphical abstract

      Square-planar iron(III) species bearing no axial ligands can still behave as spin-admixed systems (S=3/2, 5/2). The highly unusual homoleptic σ-organoiron complex [Li(thf)4][FeIII(C6Cl5)4] (see anion in picture; green Cl, gray C) is an example of such a system.

    18. Dynamical Behavior and Dipole–Dipole Interactions of Tetrafluoromethane–Water (pages 6711–6714)

      Article first published online: 15 SEP 2006 | DOI: 10.1002/anie.200602000

      Thumbnail image of graphical abstract

      Top stuff: The configuration of tetrafluoromethane–water is driven by dipole–dipole interactions rather than hydrogen bonds. The complex, which consists of a planar and a spherical moiety, is an asymmetric top in its equilibrium conformation, but its effective behavior is that of a symmetric top, owing to its high internal dynamics.

    19. Stereocontrolled Total Synthesis of Bengazole A: A Marine Bisoxazole Natural Product Displaying Potent Antifungal Properties (pages 6714–6718)

      Thumbnail image of graphical abstract

      Seeing is believing: Treatment of tryptophan with formic acid and hydrochloric acid generates a violet-blue color. The reaction is very specific, and can be used to identify tryptophan in a mixture of amino acids, or corroborate the existence of tryptophyl groups in peptides or proteins (see picture; A: blank; B: a mixture of 9 representative amino acids; C: tryptophan; D: mixture (B) and tryptophan; E: reduced glutathione; F: egg-white albumin).

      Desperately seeking silyenylium: Electrophilic attack of silylene 1 (R=2,6-diisopropylphenyl) by B(C6F5)3 and H+ afforded the silylene-like zwitterion 2 and the “free” silyliumylidene cation 3 (in the presence of the noncoordinating [B(C6F5)4] anion), respectively. Cations 2 and 3 represent a novel class of low-coordinate silicon cations with promising potential for the synthesis of heteroleptic silylenes.

      P analogues of cyclohexane: The first examples of hexaphosphorus homocyclic dications [P6Ph4R4]2+ (R=Ph, Me; see picture, P yellow, C dark gray) were prepared in a melt reaction from readily accessible starting materials in essentially quantitative yield. X-ray analysis of the dications reveals cyclohexane-like twist-boat and chair conformations of the phosphorus homocycle in the solid state.

    25. Diels–Alder Approach to Polysubstituted Biaryls: Rapid Entry to Tri- and Tetra-ortho-substituted Phosphorus-Containing Biaryls (pages 6737–6741)

      Rapid construction: A Diels–Alder-based approach to the synthesis of highly functionalized biaryls from readily available precursors is disclosed. The utility of these biaryl templates in palladium-mediated couplings is explored along with subsequent reductions of the nitro and phosphine oxide moieties. Finally, initial application of a synthesized biaryl as a highly active ligand in palladium-mediated coupling is carried out.

    26. A C3-Symmetric Palladium Catalyst with a Phosphorus-Based Tripodal Ligand (pages 6741–6744)

      Article first published online: 20 SEP 2006 | DOI: 10.1002/anie.200601084

      Thumbnail image of graphical abstract

      AC3-symmetric palladium complex formed from a new readily accessible and rigid tripodal phosphorus-based ligand has no chirality in either of its pendent arms but is intrinsically chiral (see picture). The potential of the racemic complex as a catalyst is demonstrated in several Suzuki cross-coupling reactions. The enantiomerically pure compound is also tested for asymmetric catalysis in a model reaction.

      Charge separation in the reference molecules is the main reason for the unusually high aromatic stabilization energies (ASEs) of nonclassical 1-sila-3,4-diboracyclopentanes of type 1. Compound 1 a was synthesized, and the ASE for its model compound 1 b was computed. In reference molecule 2 the two electrons, which are cyclically delocalized in 1 b, are localized in a B[BOND]B bond (R=SiMe3, Dur=2,3,5,6-tetramethylphenyl).

      A light remedy to overdosing: Aptamers with an intramolecular “caged” antisense region remain active until they are irradiated. Upon irradiation, the antisense activity is released and the aptamer refolds into an inactive structure (see scheme).

      A highly efficient transfer hydrogenation of benzoxazines, benzothiazines, and benzoxazinones with as low as 0.01 mol % binol phosphate catalyst furnishes the dihydro-2H-benzoxazines, -benzothiazines, and -benzoxazinones in good yields and with excellent enantioselectivities (see scheme). Particularly noteworthy are the mild reaction conditions and the wide scope of substrates, including sulfur-containing compounds.

      Reminiscent of a snowflake: The dimer of a hydroxy-substituted oligosilane dendrimer (see picture, left; Si yellow, C green, H white, O red) is remarkably stable according to IR spectroscopy and DFT calculations. Strong intermolecular hydrogen bonds are not only the glue that holds the “silicon snowflake” together, but are also the key to understanding the relationship between the conformation of the oligosilane backbone and its thermochromic behavior.
