perfluoroacid fluorides with a perfluoro(4-alkylpiperazinyl) group were obtained in fair to good yields from the fluorination of methylesters of 4-alkylpiperazinyl-substituted carboxylicacids. Yields of the targeted perfluoro(4-alkylpiperazinyl) group containing perfluorocarboxylic acid fluorides varied depending on both the type of N-alkyl (alkyl=CH3− or C2H5−) group at the 4-position and the (ω-methoxycarbonylalkyl)
Six methyl esters of 3-dialkylamino-substituted propionic acids were subjected to electrochemicalfluorination to give the corresponding perfluoroacid fluorides. The following dialkylamino substituents were investigated: diethylamino, di-n-propyl-amino, di-n-butylamino, pyrrolidino, morpholino and piperidino groups. These perfluoroacid fluorides, which were obtained in fair yields, are considered to
将3-二烷基氨基取代的丙酸的六种甲酯进行电化学氟化,得到相应的全氟代氟化物。研究了以下二烷基氨基取代基:二乙基氨基,二正丙基氨基,二正丁基氨基,吡咯烷基,吗啉代和哌啶子基。这些以合理收率获得的全氟酸氟化物被认为是制备软质(可降解)含氟化合物的潜在关键前体。这些盐在水溶液中显示出明显降低的表面张力。报告了所获得的所有全氟酸氟化物的物理性质,以及它们的光谱数据(19 F NMR,质谱和IR光谱)。
