Photoreduction d'esters d'acides perfluores dans l'hexamethylphosphortriamide (HMPT). Elimination selective du fluor en α du groupe carboxyle

The first example of fluorine elimination α to a carboxyl group is reported.The defluorination occurs when solution of perfluorocarboxylic esters in hexamethylphosphortriamide are irradiated with UV light (254 nm).Mechanistic and synthetic aspects of this new reaction are described.
