Synthesis of tetrafluoroethyl- and tetrafluoroethylene-containing amines by the reaction of silanes with enamines under acidic conditions

Enamines with in situ formed hydrogen fluoride underwent efficient reaction with trimethyl(1,1,2,2tetrafluoro-2-(phenylthio)ethyl)silane and trimethyl(1,1,2,2-tetrafluoro-2-(phenylsulfonyl)ethyl)silane. Radical or reductive desulfurization of the addition products provided amines containing the tetrafluoroethyl group. (C) 2014 Elsevier B.V. All rights reserved.
