A process for preparing acylfluorides by reaction of carbonyl fluoride COF2 with compounds having general formula:T = CR1R2 wherein:T is O or CF2R1 and R2, equal or different, are F or a R(O)t radical, wherein R = linear or branched C1-C7 (per)fluoroalkyl, optionally containing one or more oxygen atoms, t is an integer equal to zero or 1; wherein a catalyst supported on porous compound is used, the catalyst being selected from: CsF, RbF, KF, AgF, each optionally in admixture with one or more of the others.

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.
