Hydrolysis of the imine perfluoro-5-aza-4-nonene, C3 F7-CF=N-C4F9, in ether was studied by several spectroscopic techniques including 17O NMR. The initial product is C3F7 -CO-NH-C4F9 which is converted to (C3 F7CO)2NH and then to C3F7 CONH2 and C3F7CO2H. Solvolysis in liquid ammonia afforded the amidine C3 F7-C(=NH)NH2. Reaction with hydrazine produced 3,5-bis(heptafluoropropyl)-1,2,4-triazole whose crystal structure is reported.
