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 the kind of amino group, respectively.Better yields of perfluoroacid fluorides were obtained from methyl esters having isobutyric acid skeletons than those having n-butyric acid groups, and from the acids containing cyclic amino groups than those containing acyclic ones.

Six methyl esters of 3-dialkylamino-substituted propionic acids were subjected to electrochemical fluorination to give the corresponding perfluoroacid fluorides.The following dialkylamino substituents were investigated: diethylamino, di-n-propylamino, di-n-butylamino, pyrrolidino, morpholino and piperidino groups.These perfluoroacid fluorides, which were obtained in fair yields, are considered to be prospective key precursors for preparing soft-type (degradable) fluorochemicals.The salts show a considerable lowering of surface tension in aqueous solution.Thephysical properties of all the perfluoroacid fluorides obtained are reported, together with their spectroscopic data (19F NMR, mass and IR spectra).
