Hot Paper: Engineering Multifunctional Capsules through the Assembly of Metal–Phenolic Networks

Junling Guo, Yuan Ping, Hirotaka Ejima, Karen Alt, Mirko Meissner, Joseph J. Richardson, Yan Yan, Karlheinz Peter, Dominik von Elverfeldt, Christoph E. Hagemeyer, Frank Caruso*

Multifunctional capsules: A common plant phenolic compound, tannic acid, can be used to coordinate a variety of metals through a one-step assembly process, thereby yielding a broad library of metal–phenolic network (MPN; see picture) capsules. The properties of the MPN capsules are determined by the coordinated metals.

Hot Paper: Geminate Recombination as a Photoprotection Mechanism for Fluorescent Dyes

Hot Paper: Geminate Recombination as a Photoprotection Mechanism for Fluorescent Dyes

Phil Holzmeister, Andreas Gietl, Philip Tinnefeld*

Single-molecule spectroscopy reveals a new mechanism for diffusion-limited photoprotection. Geminate recombination after reduction of organic dyes by thiols enhances photostabilization by avoiding the buildup of photobleaching intermediates such as photo-oxidized states. Stable and long-lasting fluorescence can be achieved in combination with ROXS buffers.

VIP: Copper-Chelating Azides for Efficient Click Conjugations in Complex Media

Valentina Bevilacqua, Mathias King, Manon Chaumontet, Marc Nothisen, Sandra Gabillet, David Buisson, Céline Puente, Alain Wagner, and Frédéric Taran*

The search for fast and high-yielding bioorthogonal ligations is of prime importance in chemical biology. To this end, clickable copper complexes were designed for ultrafast ligation with alkynes in complex biological media. The reactivity and stability of one of these copper complexes allowed efficient click reaction with alkynes within seconds inside living cells.

Hot Paper: Construction of Quaternary Stereogenic Carbon Centers through Copper-Catalyzed Enantioselective Allylic Cross-Coupling with Alkylboranes

Hot Paper: Construction of Quaternary Stereogenic Carbon Centers through Copper-Catalyzed Enantioselective Allylic Cross-Coupling with Alkylboranes

Kentaro Hojoh, Yoshinori Shido, Hirohisa Ohmiya*, Masaya Sawamura*

The SN2'-type: A combination of a chiral CuI/L* catalyst system and EtOK enabled the enantioselective SN2'-type allylic cross-coupling between alkylboranes and γ,γ-disubstituted primary allyl chlorides. The reaction generates quaternary carbon stereogenic centers bearing three sp3-alkyl groups and a vinyl group. A reaction pathway involving addition/elimination of a neutral alkylcopper(I) species is proposed.

Hot Paper: Constructing 3D Branched Nanowire Coated Macroporous Metal Oxide Electrodes with Homogeneous or Heterogeneous Compositions for Efficient Solar Cells

Hot Paper: Constructing 3D Branched Nanowire Coated Macroporous Metal Oxide Electrodes with Homogeneous or Heterogeneous Compositions for Efficient Solar Cells

Wu-Qiang Wu, Yang-Fan Xu, Hua-Shang Rao, Hao-Lin Feng, Cheng-Yong Su, Dai-Bin Kuang*

Wired for light: A versatile method allows the preparation of nanowire-coated macroporous material based homo- or heterogeneous metal oxide composite electrodes (TiO2–TiO2, SnO2–TiO2, and Zn2SnO4–TiO2). Dye-sensitized solar cells based on macroporous TiO2/TiO2 nanowire homogeneous electrode show an impressive conversion efficiency as high as 9.51 %, which is much higher than those of pure macroporous material based photoelectrodes used up to date.

Hot Paper: Controlled Electropolymerization of Ruthenium(II) Vinylbipyridyl Complexes in Mesoporous Nanoparticle Films of TiO2

Hot Paper: Controlled Electropolymerization of Ruthenium(II) Vinylbipyridyl Complexes in Mesoporous Nanoparticle Films of TiO2

Zhen Fang, Shahar Keinan, Leila Alibabaei, Hanlin Luo, Akitaka Ito, Thomas J. Meyer*

Growth on the surface: Ruthenium(II) vinylpolypyridyl assemblies within the cavities of mesoporous nanoparticle TiO2 films have been grown from the surface by stepwise, electrochemically controlled radical polymerization. This polymerization was monitored by cyclic voltammetry as well as UV/Vis and X-ray photoelectron spectroscopy.

Hot Paper: Arylphosphonylation and Arylazidation of Activated Alkenes

Hot Paper: Arylphosphonylation and Arylazidation of Activated Alkenes

Wangqing Kong, Estíbaliz Merino, Cristina Nevado*

Radical difunctionalization: The addition of heteroatom-centered radicals to the double bond of arylsulfonyl acrylamides furnishes alkyl radical intermediates. A reaction cascade is then triggered so that α-aryl-β-heterofunctionalized amides with a quaternary stereocenter are obtained by the simultaneous formation of C–C and C–P/C–N bonds across the double bond. Heterofunctionalized oxindoles can also be synthesized.

Yumeng Xi, Boliang Dong, Edward J. McClain, Qiaoyi Wang, Tesia L. Gregg, Novruz G. Akhmedov, Jeffrey L. Petersen, Xiaodong Shi*

Less basic, less hindered: The gold-catalyzed intermolecular Markovnikov addition of sulfinic acids to terminal alkynes has been achieved through the use of a bimetallic gold/gallium catalyst system. Various α-substituted vinyl sulfones were efficiently synthesized. A one-pot synthesis that starts from the bench-stable sodium sulfinates was also developed (DCE=1,2-dichloroethane).

Hot Paper: Fusing N-Heterocyclic Carbenes with Carborane Anions

Hot Paper: Fusing N-Heterocyclic Carbenes with Carborane Anions

Ahmad El-Hellani, Vincent Lavallo*

Three in one: A novel family of polyanionic N-heterocyclic carbene–lithium adducts are reported, that feature two N-bonded weakly coordinating carborane anions. Judicious choice of base allows the selective deprotonation of an anionic imidazolium to form either a normal C2 or an abnormal C5 imidazolylidene. When treated with nBuLi the monoanionic imidazolium produces a doubly deprotonated trianionic C2,C5 dilithium complex.
