A process for preparing acylfluorides

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.

Carbon-chain isomerization during the electrochemical fluorination in anhydrous hydrogen fluoride - A mechanistic study

The compounds i-C4H9SO2F, i-C3H7SO2F and cyclo-C3 H7C(O)F have been subjected to electrochemical fluorination in anhydrous hydrogen fluoride. The resulting products were fully analyzed by NMR spectroscopy. From the reaction balances, literature data and quantum chemical calculations, a new mechanism for carbon-chain isomerization during the electrochemical fluorination (ECF) is proposed. The key step in the formation of isomeric products is believed to be a ring closure reaction involving carbo-cationic or biradical intermediates.

The electrochemical fluorination of N-containing carboxylic acids (Part 4). Fluorination of methyl 3-dialkylamino-isobutyrates and methyl 3-dialkylamino-n-butyrates

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.

SYNTHESIS AND TRANSFORMATIONS OF PERFLUORO(2,4-DIMETHYL-3-HEPTENE) OXIDE

The oxidation of perfluoro(2,4-dimethyl-3-heptene) was realized with aqueous solutions of sodium hypohalites.The reaction of the obtained perfluoro(2,4-dimethyl-3-heptene) oxide with nucleophilic and electrophilic reagents was studied.Attack on the epoxide ring of perfluoro(2,4-dimethyl-3-heptene) oxide is hindered with increase in the size of the nucleophile.Perfluoro(2,4-dimethyl-3-heptene) oxide exhibits high stability toward electrophiles.
