Several methylesters of 3-dialkylamino-substituted n- and isobutyric acids have been subjected to electrochemical fluorination to give the corresponding perfluoroacid fluorides. Dimethyl, diethyl, pyrrolidino, morpholino, piperidino and N-methylpiperazino groups were investigated as dialkylamino substituents. The structure/yield relationship was evaluated both in terms of the structure of the acid and

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.
