PRECISION OF DISCLOSURE: The invention relates to a functionalization method of a perfluorinated radical consisting in reacting a perfluoro-haloalkane of formula RFX, in which the radical RF represents a straight or branched perfluorinated alkyl chain, saturated or not, containing from 2 to 12 carbon atoms, and X a chlorine, bromine or iodine atom, on a suitable reagent in the presence of a dispersion in a sulfoxylated solvent of a metallic couple composed of a metal M1 chosen from the groups 2a, 1b, 2b or 3a of the periodic table, and of a metal M2 having such an electrochemical potential in particular be used for the manufacture of acid derivatives RFCOOH perfluorocarboxylic and perfluoroalkanesulfinic RFSO2M. |
