Abstract
A process for the preparation of an ester, especially fluorinated esters R.sub.1 O.OC--CHR.sub.2 --CO.OR.sub.3, R.sub.1 and R.sub.3 are each independently selected from alkyl, cycloalkyl and aryl. R.sub.2 is selected from hydrogen, alkyl, cycloalkyl. The method includes the steps of covering a corresponding compound of formula 2: R.sub.1 O.OC--CHR.sub.2 --CO.OR.sub.3 in the presence of a base, of salt of a compound of formula 2, into corresponding compound of formula 1 by the reaction of elemental fluorine.
