A method for preparing a partially fluorinated ester comprising acyl and alkoxy groups wherein the acyl group comprises a branched or linear fluorine containing C 3 -C 8 group with one of the structures: (Formulae (I), (II)) wherein X and Y are independently selected from: —H, —CH 3 , —F, —Cl, —CH 2 F, —CF 3 —OCF 3 , —OCH 2 CF 3 , OCH 2 CF 2 CHF 2 and —CH 2 CF 3 (wherein both X and Y cannot be H) comprising reacting an unsaturated halocarbon: (Formula (III)) wherein A and B are independently selected from the group comprising —H, —CH 3 , —F, —Cl, —CH 2 F, —CF 3 , —OCF 3 , —OCH 2 CF 3 , OCH 2 CF 2 CHF 2 and —CH 2 CF 3 (wherein both A and B cannot be H) with carbon monoxide and an alcohol, in the presence of a catalyst methods. |
