Imines have been prepared using three different methods. The thermal addition of tetrafluoroethylene to N-bromoperhalo-1-alkanimines (RfCF=NBr) to give imines of the type RfCF= NCF2CF2Br, the Lewis acid cleavage of perfluorinated amines to give imines of the type RfN=CFRf' and the one pot reaction between hexafluoroacetone and perfluoroamides. Reactions of these imines with m-chloroperoxy benzoic acid (MCPBA) lead to the corresponding cis-perfluoro-2,3-dialkyloxaziridines RfN-ORF'. The oxaziridines undergo cycloadditions with olefins to give the corresponding oxazolidines. A preliminary investigation was done on the synthesis and reaction chemistry of complex formed between activated zinc and the 4-iodo and 4-bromo-perhalooxazolidines.
