Abstract Aziridines I react with trifluoromethyl hypofluorite at− 40 C to produce mixtures of 1- (aziridine) carbonyl fluoride II and 1-fluoroaziridine III, the proportions of which depend on steric effects. Several compounds II react with starting materials to give 1, 1′-(carbonyl) bisaziridines IV. Most compounds II and all compounds IV are isolated. Chemical properties and ir and nmr data of II, III, IV are described; the formation of an isocyanate and a ...
