摘要

Introduction of a polyfluoroalkyl group into aromatic compounds was achieved by Friedel-Crafts reaction using (1-chloro-1-hydroperfluoroalkyl) sulfides 1, and the subsequent desulfurizing-difluorination of the resulting product using IF(5)/Et(3)N-nHF. Perfluoroethyl, 1,1,2,2,3,3-hexafluoropropyl, and 1,1,2,2,3,3,4,4,5,5-decafluoropentyl groups were introduced to various aromatic compounds by this method. Selective perfluoroethylation of uracil at the 5-position was also performed.
