Photoreduction in hexamethylphosphortriamide was found to be an efficient method to selectively reduce C-F bonds α to the carboxyl group of alkyl perfluoroesters.The reation proceeds by photoinduced electronic transfer from the excited phosphoramide.Conditions were found to remove selectively one fluorine and the reaction was applied to the synthesis of alkyl 2-hydro perfluoroesters.
