A method for preparing a partially fluorinated ester comprising acyl and alkoxy groups wherein the acyl group comprises a branched or linear fluorine containing C3-C8 group with one of the structures: (Formulae (I), (II)) wherein X and Y are independently selected from: -H, -CH3, -F, -Cl, -CH2F, -CF3 -OCF3, -OCH2CF3, OCH2CF2CHF2 and -CH2CF3 (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, -CH3, -F, -Cl, -CH2F, -CF3, -OCF3, -OCH2CF3,OCH2CF2CHF2 and -CH2CF3 (wherein both A and B cannot be H) with carbon monoxide and an alcohol, in the presence of a catalyst.methods |
