Chemistry of N-substituted 2,2-difluoro-3,3-bis (trifluoromethyl)aziridines

Variety of N-Aryl and N-alkyl-2,2-difluoro-3,3-bis(trifluoromethyl)aziridines are prepared by reaction of the corresponding imines of hexafluoroacetone with difluorocarbene generated by thermolysis of hexafluoropropylene oxide. Results of reaction of N-aryl-2,2-difluoro-3,3-bis(trifluoromethyl)-aziridines with CsF, CF3SO3H, HF and thermal rearrangement are presented.
