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.

The reaction of N-arylimines of hexafluoroacetone and CF3Si(CH3)3 (1) in the presence of CsF results in a 48–84% yield formation of ArN(H)C(CF3)3. The reaction requires an equimolar amount of CsF and rapidly proceeds in solvents such as THF or monoglyme. Interaction of CF3NC(CF3)2 with excess of 1 leads to the formation of novel amine [(CF3)3C]2NH. Stable salt of this amine is isolated in a reaction
