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.
