Treatment of perfluoro-2-nitrosopropane and perfluoronitrosocyclobutane with aqueous potassium bisulphite yields the oximes of perfluoroacetone and perfluorocyclobutanone, respectively; the nitroso-compounds are easily prepared via indirect addition of nitrosyl fluoride across the double bonds in perfluoropropene and perfluorocyclobutene.
diaziridine 2c is rearranged in these conditions with ring-expansion. Complete asymmetric transformation has been found to take place on the formation of the solid phase of diastereomers 2d and 2j, and a closed cycle of diastereomeric transformations has been accomplished. Diaziridine 2g with chiral centres only at the nitrogen atoms has been obtained with the optical purity of 85.5% by resolution via

The1H NMR spectra ofO-derivatives of 1-hydroxy-2,2-bis(trifluoromethyl)aziridine containing such substituents as EtO2CCH2, (R/S)-RO2CCH(Me) (R=Me, Pri, or But), (R/S)-H2NC(O)CH(Me), and (R)-H2NC(O)CH(Me) were analyzed. Both of the diastereomerically pure amides of the latter type were isolated. The validity of the1H NMR criteria, which were suggested for the determination of absolute configurations
