Prize-winning chemistry!

The Nobel Prize in Chemistry 2014 has been awarded jointly to Eric Betzig, Howard Hughes Medical Institute, Ashburn, VA, USA, Stefan W. Hell, Max Planck Institute for Biophysical Chemistry, Göttingen, and German Cancer Research Center, Heidelberg, Germany, and William E. Moerner, Stanford University, CA, USA, "for the development of super-resolved fluorescence microscopy".

Work from Stefan Hell and his group on masked rhodamine dyes and their applications in light microscopy applications was recently highlighted on the front cover of Chemistry—A European Journal.

    Dream Reactions: The nickel-catalyzed one-pot carboxylation of alkenes with CO2 allows the direct and selective synthesis of a wide range of unsaturated carboxylates from alkenes and alkadienes in high selectivity.

  2. Rhodium(III)- and Iridium(III)-Catalyzed C7 Alkylation of Indolines with Diazo Compounds

    Wen Ai , Xueyan Yang, Yunxiang Wu, Xuan Wang, Prof. Yuanchao Li, Dr. Yaxi Yang and Dr. Bing Zhou

    Article first published online: 30 OCT 2014 | DOI: 10.1002/chem.201405077

    A RhIII-catalyzed procedure for the C7-selective C[BOND]H alkylation of indolines with α-diazo compounds at room temperature is reported. An IrIII-catalyzed intermolecular insertion of arene C[BOND]H bonds into α-diazo compounds has also been successfully developed (see scheme; EWG=electron-withdrawing group).

  3. Coordination and Activation of Al[BOND]H and Ga[BOND]H Bonds

    Joseph A. B. Abdalla, Dr. Ian M. Riddlestone, Joshua Turner, Paul A. Kaufman, Remi Tirfoin, Dr. Nicholas Phillips and Prof. Simon Aldridge

    Article first published online: 30 OCT 2014 | DOI: 10.1002/chem.201405018

    The modes of interaction of aluminium and gallium hydrides towards 14- and 16-electron transition-metal fragments were investigated. More electron-rich N-heterocyclic carbene compounds (NHC⋅EH3; E=Al or Ga) uniformly generate κ2 σ-complexes. By contrast, β-diketiminato (nacnac)-stabilized systems, {HC(MeCDippN)2}EH2, show more diversity, including examples of unprecedented E[BOND]H bond activation.

  4. A Multi-Addressable Switch Based on the Dimethyldihydropyrene Photochrome with Remarkable Proton-Triggered Photo-opening Efficiency

    Dr. Diego Roldan, Dr. Saioa Cobo, Dr. Frédéric Lafolet, Dr. Neus Vilà, Dr. Constance Bochot, Dr. Christophe Bucher, Prof. Dr. Eric Saint-Aman, Dr. Martial Boggio-Pasqua, Dr. Marco Garavelli and Prof. Dr. Guy Royal

    Connect four: Pyridine-substituted dimethyldihydropyrene (DHP) photochromes have been synthesized and their photoisomerization leading to the corresponding cyclophanediene (CPD) isomer has been investigated. Quaternization of the pyridine units by protonation or methylation was found to greatly enhance the photochromic properties. The CPD to DHP ring-closure reaction can be triggered by oxidation of the CPD unit.

  5. Novel Composite Plastics Containing Silver(I) Acylpyrazolonato Additives Display Potent Antimicrobial Activity by Contact

    Prof. Fabio Marchetti, Dr. Jessica Palmucci, Prof. Claudio Pettinari, Dr. Riccardo Pettinari, Dr. Francesca Condello, Dr. Stefano Ferraro, Dr. Mirko Marangoni, Prof. Alessandra Crispini, Dr.  Stefania Scuri, Prof.  Iolanda Grappasonni, Prof. Mario Cocchioni, Dr. Massimo Nabissi, Dr. Michele R. Chierotti and Prof. Robetro Gobetto

    Article first published online: 30 OCT 2014 | DOI: 10.1002/chem.201404812

    Touch of (cell) death: Novel silver(I) acylpyrazolonato compounds were embedded on polyethylene matrix and the antimicrobial activity of the composite materials was tested against E. coli, P. Aeruginosa, and S. aureus (see figure). The composites show efficient inhibition of bacteria growth on the contact surface, exceeding 90 % reduction of bacteria within a few hours of exposure. The materials containing silver(I) coordination polymers as additives exert their antimicrobial action by simple contact, without release of the silver ions.
