1,1-Difluoroethysilanes (R3SiCF2CH3, R=Me or Et) were synthesized from 1,1-difluoroethyl phenyl sulfone and chlorosilanes using magnesium metal via reductive 1,1-difluoroethylation. It was confirmed that 1,1-difluoroethylsilanes were effective 1,1-difluoroethylating reagents for carbonyl compounds. (C) 2007 Elsevier B.V. All rights reserved.

Facile Preparation of Fluorine-containing Alkenes, Amides and Alcohols <i>via</i> the Electrophilic Fluorination of Alkenyl Boronic Acids and Trifluoroborates
Reaction of alkenyl boronic acids, or preferably alkenyl trifluoroborates, with one equivalent of SelectfluorTM gives the corresponding alkenyl fluorides. A similar reaction with two equivalents of SelectfluorTM in water or a nitrile solvent gives difluoromethyl-substituted alcohols and amides respectively.
