Electrochemical fluorination of N-cyclopentylpyrrolidine gave the corresponding F-amine together with a ring-opened compound N-(F-pentyI)-F-pyrrolidine in the ratio of 1 to 1, in 55% yield. N-cyclohexylpyrrolidine, N-cyclopentylpiperidine, and N-cyclohexylpiperidine were also eletrochemically fluorinated in the same manner to give the corresponding F-amines, their isomers with rearranged structures

Treatment of several kinds of perfluoro (N-alkyl-cyclic amines) (-pyrrolidines, -morpholines, -piperidines and -hexahydroazepin) with oleum at 140 ∼ 170 °C afforded the corresponding perfluorolactams in fair yields. The reaction conditions and the properties of perfluorolactams are described.
