Aziridines I react with trifluoromethylhypofluorite at − 40°C to produce mixtures of 1-(aziridine)carbonylfluoride 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

Novel classes of trifluoromethylvinylaziridines have been prepared. Addition of dimethylacetylenedicarboxylate to a 2-trifluoromethyl-aziridine gives 2(2-trifluoromethylaziridin-1-yl)fumarate. Vinylic substitution of different β-chlorotrifluoroenones produces 4-aziridin-1-yl-1,1,1-trifluorobut-3-en-2-one or 3-trifluoromethyl-3-aziridin-1-yl enone. The relative configuration of these compounds was established
