Abstract: Novel ruthenium carbene complexes bearing unsymmetrical NHC-ligands based on N-alkyl-N´-arylimidazoline with hexafluoroisopropylmethoxy group in para-position of N-aryl moiety have been synthesized. Catalytic activity of complexes obtained was investigated on model reactions of intra- and intermolecular… read more here.

DOI: 10.1016/j.mencom.2020.01.034
Abstract: Crystal structures of fluorinated alkyl tosylates TsOCH2CF2CHFCF3 and TsOCH2(CF2)3CHF2 have been characterized by X-ray diffraction and quantum chemical calculations. The calculations have revealed the stabilization of head-to-tail conformation for TsOCH2CHFCF2CF3 due to intramolecular F・・・p and… read more here.

Abstract: The 1,1,2,2-tetrafluoroethylene unit is prevalent in bioactive molecules and functional materials. Despite being in principle a straightforward strategy to access this motif, the direct tetrafluorination of alkynes involves very hazardous or inconvenient reagents. Therefore, safer… read more here.
