Several methyl esters 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
3-二烷基氨基取代的正丁酸和异丁酸的几种甲酯已经进行了电化学氟化反应,得到了相应的全氟代氟化物。研究了作为二烷基氨基取代基的二甲基,二乙基,吡咯烷基,吗啉代,哌啶子基和N-甲基哌嗪子基团。分别根据酸的结构和氨基的种类评价了结构/产率关系。由具有异丁酸骨架的甲酯比具有正丁酸基团的甲酯得到的全氟氟化物的收率更高,并且由具有环状氨基的酸得到的无氟氟化物的收率更高。
