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
N-环戊基吡咯烷的电化学氟化以1∶1的比例得到相应的F-胺和开环的化合物N-(F-pentyI)-F-吡咯烷,产率为55%。N-环己基吡咯烷,N-环戊基哌啶和N-环己基哌啶也以相同的方式进行电子氟化,得到相应的F-胺,其重排结构的异构体和开环的胺,比率为-4:2:1 ,和2:1:1分别以51%至53%的收率。提供了支持的光谱数据。
