New methods for perfluoroalkylation of carbon-nitrogen double bonds have been developed. Addition of (trifluoromethyl)trimethylsilane (TMSCF3) to α,N-diarylnitrones produced α series of α-(trifluoromethyl)-N hydroxyl amines protected as their O-trimethylsilyl derivatives. An alternate procedure using pentafluoroethyllithium (F5C2L1) and chlorotrimethylsilane (TMSCI) afforded O-trimethylsilyl-α-(pentafluoroethyl)-N-hydroxyl amines.
