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.

  1. Rhodium Bis(quinolinyl)benzene Complexes for Methane Activation and Functionalization

    Ross Fu, Matthew E. O'Reilly, Robert J. Nielsen, William A. Goddard III  and T. Brent Gunnoe

    Article first published online: 21 NOV 2014 | DOI: 10.1002/chem.201405460

    Activating methane: Free-energy activation and functionalization barriers were calculated for a series of rhodium(III) bis(quinolinyl)benzene (bisqx) complexes for partial oxidation of methane. An η2-benzene coordination mode encourages methyl group functionalization by serving as an effective leaving group for SN2 and SR2 attack.

  2. An Efficient Synthesis of Porphyrins with Different meso Substituents that Avoids Scrambling in Aqueous Media

    Dr. Agnieszka Nowak-Król, Rémi Plamont, Dr. Gabriel Canard, Judicaelle Andeme Edzang, Prof. Dr. Daniel T. Gryko and Prof. Dr. Teodor Silviu Balaban

    Article first published online: 21 NOV 2014 | DOI: 10.1002/chem.201403677

    No scrambling in water! Not only bilanes but also porphyrinogens can be effectively prepared in H2O/EtOH and H2O/THF mixtures. Because in the presence of water there is no scrambling, the corresponding meso-substituted porphyrins can be prepared in a straightforward manner. Both aromatic and arylpropargyl aldehydes can be effectively employed with dipyrromethanes (see figure) to give a plethora of π-extended porphyrins.

  3. A Computational Study of Vicinal Fluorination in 2,3-Difluorobutane: Implications for Conformational Control in Alkane Chains

    Dr. Stephen J. Fox, Dr. Stephanie Gourdain, Anton Coulthurst, Claire Fox, Dr. Ilya Kuprov, Prof. Jonathan W. Essex, Dr. Chris-Kriton Skylaris and Dr. Bruno Linclau

    Article first published online: 21 NOV 2014 | DOI: 10.1002/chem.201405317

    It does compute: In contrast to 1,2-difluoroethane, the fluorine gauche effect is not the determining factor in the conformational profile of either of the 2,3-difluorobutane diastereomers. Even the conformation of the threo-isomer with the methyl groups in anti and fluorine atoms in gauche position is not the most populated in vacuum or water. An explanation is proposed.

  4. Chiral Calcium–BINOL Phosphate Catalyzed Diastereo- and Enantioselective Synthesis of syn-1,2-Disubstituted 1,2-Diamines: Scope and Mechanistic Studies

    Dr. Claudia Lalli, Audrey Dumoulin, Clément Lebée, Dr. Fleur Drouet, Vincent Guérineau, Dr. David Touboul, Prof. Dr. Vincent Gandon, Prof. Dr. Jieping Zhu and Dr. Géraldine Masson

    Article first published online: 21 NOV 2014 | DOI: 10.1002/chem.201405286

    Carbon–nitrogen bond formation: A highly efficient electrophilic amination of enamides catalyzed by a chiral calcium–phosphate complex has been developed. In general, syn-1,2-diamines were obtained in high yields with excellent diastereo- and enantioselectivities (see scheme; MS=molecular sieves). A combined approach of NMR spectroscopy, MS analysis, and DFT calculations was utilized to obtain better insight into the mechanistic features of the calcium-catalyzed amination reaction.

  5. Acid/Base-Triggered Switching of Circularly Polarized Luminescence and Electronic Circular Dichroism in Organic and Organometallic Helicenes

    Nidal Saleh, Barry Moore II, Monika Srebro, Nicolas Vanthuyne, Loïc Toupet, J. A. Gareth Williams, Christian Roussel, Kirandeep K. Deol, Gilles Muller, Jochen Autschbach and Jeanne Crassous

    Article first published online: 21 NOV 2014 | DOI: 10.1002/chem.201405176

    Rollover platination: A [6]helicene-bipyridine derivative has been used as a proligand for “rollover” cycloplatination and for the conception of acid/base chiroptical switches. Protonation triggers a change in the nature of the HOMO–LUMO transition, from a π–π* to a charge-transfer transition, and significantly modifies the circularly polarized luminescence and electronic circular dichroism spectra of the organic and organometallic helicenes (see figure).
