1. A method for preparing a partially fluorinated ester comprising acyl and alkoxy groups wherein the acyl group comprises a branched or linear fluorine containing C4-C8 group with one of the structures:

OG Complex Work Unit Chemistry
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 (wherein both X and Y cannot be H)
comprising reacting an unsaturated halocarbon:

OG Complex Work Unit Chemistry
wherein A and B are independently selected from the group comprising —H, —CH3, —F, —Cl, —CH2F, —CF3, —OCF3, —OCH2CF3, OCH2CF2CHF2 and —CH2CF3, wherein both X and Y cannot be H, with with carbon monoxide and an alcohol, in the presence of a catalyst.
