Abstract

Abstract: In an efficient procedure the nucleophilic trifluoromethylation and pentafluoroethylation of alkyl triflates using (trifluoromethyl)-and (pentafluoroethyl) trimethylsilane in the presence of anhydrous tetramethylammonium fluoride is achieved giving 71-80% isolated yields. Key words: perfluoroalkylation,(perfluoroalkyl) trimethylsilane, anhydrous tetramethylammonium fluoride, nucleophilic substitution
