Abstract
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.
Claims11
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:
- 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:
- 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.
