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. Synthesis of Single-Crystalline Spinel LiMn2O4 Nanorods for Lithium-Ion Batteries with High Rate Capability and Long Cycle Life

    Xiuqiang Xie, Dr. Dawei Su, Dr. Bing Sun, Jinqiang Zhang, Prof. Dr. Chengyin Wang and Prof. Dr. Guoxiu Wang

    Article first published online: 22 OCT 2014 | DOI: 10.1002/chem.201404171

    Long-lived LIBs: Single-crystalline LiMn2O4 nanorods were prepared by a vacuum-assisted impregnation method followed by solid-state reaction. The as-prepared LiMn2O4 nanorods exhibited high rate capability and retained 95.6 % of the initial capacity after 1000 cycles as cathode materials for lithium-ion batteries (LIBs). This work can pave the way for developing LiMn2O4-based LIBs with long cycle life.

  2. HP-CsB5O8: Synthesis and Characterization of an Outstanding Borate Exhibiting the Simultaneous Linkage of All Structural Units of Borates

    Gerhard Sohr, Daniel M. Többens, Prof. Dr. Jörn Schmedt auf der Günne and Prof. Dr. Hubert Huppertz

    Article first published online: 22 OCT 2014 | DOI: 10.1002/chem.201404018

    What′s new in borates? The high-pressure borate HP-CsB5O8 was synthesized at 6 GPa and 900 °C. Its new structure type is the second example of an outstanding combination of the main structural units of borates in one compound (see figure). Temperature-programmed X-ray powder diffraction, vibrational spectroscopy, and solid-state 11B NMR measurements provide further insight into this fascinating new compound.

  3. Phosphorus-Stabilized Titanium Carbene Complexes: Synthesis, Reactivity and DFT Studies

    Mathieu Lafage, Dr. Hadrien Heuclin, Dr. Xavier-Frédéric Le Goff, Dr. Nathalie Saffon-Merceron and Dr. Nicolas Mézailles

    Article first published online: 22 OCT 2014 | DOI: 10.1002/chem.201403708

    A titanium carbene complex, [(SCS)TiCl2(thf)] carbene (see Scheme), synthesized from the geminal dianion bis(thiophosphinoyl)methanediide (SCS2−), reacts with N,N′-dicyclohexylcarbodiimide to form a ketenimine and the Ti imido complex under very mild conditions. DFT calculations rationalize this unprecedented reactivity.

  4. Lewis and Brønsted Acid Cocatalyzed Reductive Deoxyallenylation of Propargylic Alcohols with 2-Nitrobenzenesulfonylhydrazide

    Zhaohong Liu, Dr. Peiqiu Liao and Prof. Xihe Bi

    Article first published online: 21 OCT 2014 | DOI: 10.1002/chem.201404692

    Better together: A novel and highly efficient Lewis and Brønsted acid cocatalyzed reductive deoxyallenylation of propargylic alcohols with 2-nitrobenzenesulfonylhydrazide (NBSH) has been developed (see scheme). Diverse tertiary and secondary propargylic alcohols participated in the reaction, affording various mono-, di-, and trisubstituted allenes in good-to-excellent yields. Furthermore, the synthesis of 2H-chromenes and 1,2-dihydroquinolines demonstrated the synthetic utility of this method.

  5. Inclusion of Two Different Guest Molecules within a Rationally Designed Macrocyclic Boronic Ester in Organic Solvent

    Yuji Kikuchi, Dr. Kosuke Ono, Dr. Kohei Johmoto, Dr. Hidehiro Uekusa and Prof. Dr. Nobuharu Iwasawa

    Article first published online: 21 OCT 2014 | DOI: 10.1002/chem.201405163

    The host with the most: The inclusion of two different neutral guest molecules in a macrocyclic boronic ester host is realized in organic solvent utilizing only π-stacking interactions. The host syn-1 is constructed from a newly designed fluorene tetrol and 2,7-pyrenediboronic acid and is shown to include one molecule each of dinitronaphthalimide and pyrene as a pair of electron-deficient and electron-rich aromatic molecules.
