本文报道在连二亚硫酸钠引发RFI与吡咯反应, 得到高得率的α-全氟烷基吡咯, 但产物在室温中极不稳定, 所以在产物中加入无水碳酸钾可使产物长期室温避贮存。再用甲醇钠-甲醇与2-全氟烷基吡咯反应, 可得稳定的产物。

关键词: 引发剂, 亚磺化, 吡咯 P, 脱卤反应, 全氟代烃, 连二亚硫酸钠

Under sulfinatodeiodination conditions perfluoroalkyl iodides reacted with pyrrole to give high yields of a-perfluoroalkyl pyrroles which are unstable at room temperature due to the ready hydrolysis of the a-CF2 group. On reaction with NaOMe/MeOH, the pyrroles were converted into the corresponding stable, a-dimethoxy derivatives and characterized.

Key words: PYRROLE P, INITIATOR, DEHALOGENATION REACTION, SULFINATION, PERFLUORO-HYDROCARBON, SODIUM DITHIONITE
