ChemPlusChem 6/2013: An Unconventional Anion
1521-3765/homepage/news/cplu_6b.png)
New ionic liquids and solid-state electrolytes that incorporate the carbamoylcyano(nitroso)methanide anion have been investigated by Jennifer Pringle et al. The anion can exist in both a syn and anti conformation, contributing to its useful properties such as low viscosity and good conductivity. In their Communication, Honggang Fu et al. describe a combined liquid–liquid interface reaction and the self-assembly of Co clusters to synthesize free-standing ultrathin Co nanosheets, which have ferromagnetic behavior and potential application in catalysis and nanodevices. Among the Full Papers is a report from Koen Binnemans et al. outlining the preparation and isolation of simple silver-containing ionic liquids, which show advantageous electrochemical behavior in terms of electrodeposition of crack-free silver coatings.

- A Functional Model for the Rieske Center: Full Characterization of a Biomimetic N-Ligated [2Fe-2S] Cluster in Different Protonation States

Give and take both: A bis(benzimidazolate)-capped biomimetic [2Fe-2S] cluster has been characterized in different protonation states, both in the diferric and mixed-valent forms. Protonation does not lead to structural changes of the [2Fe-2S] core, but facilitates its reduction and causes pronounced valence localization in the mixed-valent state. Concerted proton and electron transfer back to the diferric cluster emulates a key step in the function of mitochondrial Rieske proteins (see scheme).
- In Situ Generation of PhI+CF3 and Transition-Metal-Free Oxidative sp2 C

These things are sent to tri us: The introduction of CF3 units into organic molecules is important and requires the development of convenient trifluoromethylating reagents. Here, PhI+CF3, an acyclic electrophilic “CF3+” species, is described, including its in situ generation from TMSCF3, PhI(OAc)2, and KF and its direct applications in sp2 C
H trifluoromethylations under mild transition-metal-free conditions (see scheme). - Cobalt-Catalyzed Hydrosilation/Hydrogen-Transfer Cascade Reaction: A New Route to Silyl Enol Ethers
Dr. Thomas W. Lyons and Prof. Maurice Brookhart
Article first published online: 18 JUN 2013 | DOI: 10.1002/chem.201301502

Capitalizing on cobalt: A new route to silyl enol ethers employing a Co-catalyzed cascade reaction featuring a tandem hydrosilation/hydrogen-transfer reaction is reported. The low catalyst loading, mild reaction conditions, and unique η2-silane resting state showcase the impressive utility of this seldom used transition-metal catalyst in C
H activation reactions (see scheme). - Platinum(II) and Gold(III) Allenylidene Complexes: Phosphorescence, Self-Assembled Nanostructures and Cytotoxicity
Xin-Shan Xiao, Wai-Lun Kwong, Dr. Xiangguo Guan, Chen Yang, Prof. Dr. Wei Lu and Prof. Dr. Chi-Ming Che
Article first published online: 18 JUN 2013 | DOI: 10.1002/chem.201301481

The bright side of triple double bonds: Two series of stable tridentate cyclometalated PtII and AuIII allenylidene complexes were found to exhibit many functionalities, such as long-lived excited states, self-assembling into supramolecular nanostructures, DNA and nucleus binding and cellular imaging capabilities (see figure).
- First X-Ray Crystal Structure and Internal Reference Diffusion-Ordered NMR Spectroscopy Study of the Prototypical Posner Reagent, MeCu(SPh)Li(THF)3

Grow slow: The usual direct treatment of MeLi and CuSPh did not yield X-ray quality crystals of MeCu(SPh)Li. An indirect method starting from Me2CuLi⋅LiSPh and chalcone afforded the desired crystals by the slow reaction of the intermediate π-complex (see scheme). This strategy produced the first X-ray crystal structure of a Posner cuprate. A complementary NMR study showed that the contact ion pair was also the main species in solution.
