The oxaziridine CF3-cyclo-NCF2O (1) cycloadds to various 1,1-difluoroolefins under mild conditions, forming perhalo-1,3-oxazolidines, and dialkyl ketones, forming the corresponding 1,3,4-dioxazolidines.Reaction of 1 with trimethylsilyl cyanide results in the formation of (CH3)3SiN=C=NCF3 and COF2, but 1 is unreactive with other alkyl nitriles and isocyanides.With 2,5-dimethylfuran and 2,3-dimethylbutene, 1 reacts rapidly and under mild conditions ( ca. - 50 deg C) to yield CF3N=CF2 and organic products derived from the transfer of a single oxygen atom.
