The base-catalyzed reaction of cycloalkanone oximes (la,b) with perfluoro-2-methyl-2-pentene (PFMP) initially affords the addition products,i.e., fluoroalkyl ethers (2a,b). In the presence of KOH, the latter undergoes dehydrofluorination to give perfluoroalkenyl ethers (3a,b). Thermolysis of ethers3a,b results in compounds of two types — pyrrolines (4a,b) andN-perfluoroalkenyl lactams (5a,b). The latter
