Summary:Process for the preparation of perfluoroalkylated phenol derivatives by reacting, in a first stage, a phenol derivative and sulphur dioxide with a metal chosen from zinc, aluminium, manganese, cadmium or iron in a polar aprotic solvent followed, in a second stage, by adding a perfluoroalkyl bromide or iodide. LA PRESENTE INVENTION CONCERNE UN PROCEDE DE PREPARATION DE DERIVES PHENOLIQUES PERFLUOROALKYLES PAR REACTION, DANS UNE PREMIERE ETAPE, D'UN DERIVE PHENOLIQUE, DE DIOXYDE DE SOUFRE AVEC UN METAL CHOISI PARMI LE ZINC, L'ALUMINIUM, LE MANGANESE, LE CADMIUM, LE FER, DANS UN SOLVANT APROTIQUE POLAIRE SUIVIE, DANS UNE DEUXIEME ETAPE, PAR L'ADDITION D'UN BROMURE OU D'UN IODURE DE PERFLUOROALKYLE.
