A process for the preparation of an ester, especially fluorinated esters R1O.OC-CFR2-CO.OR3.R1 and R3 are each independently selected from alkyl, cycloalkyl and aryl. R2 is selected from hydrogen, alkyl, cycloalkyl. The method includes the steps of covering a corresponding compound of formula 2: R1O.OC-CHR2-CO.OR3 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. |
