fair yield from the fluorination of 3 along with F-[(methylpiperidino)-acetylfluoride] which was formed as a result of the isomerization of 3 during fluorination. In addition, several derivatives of 4 were synthesized. F-(1-iodomethyl-hexahydroazepine) (4a) was prepared by the reaction of 4 with anhydrous LiI. The compound 4 was converted into its potassium salt (4c) via methyl F-(1-hexahydroazepine-acetate)

The directfluorination of hexamethyleneimine, heptamethyleneimine, 2,6-dimethylmorpholine, thiomorpholine, 1,4-dimethylpiperazine and piperazine produced the corresponding perfluorinated products. The 19F NMR spectrum of perfluoro N,N1-difluoropiperazine was found to be temperature- dependent.
