No. WO97/43231 PCT Pub. Date Nov. 20, 1997The invention features a useful method for the synthesis of fluorinated derivatives. It is characterized in that it comprises at least one step in which a substrate comprising one sp3 hybridizing halogenophore carbon bearing at least two halogens, at least one of which is a halogen of an atomic number higher than that of fluorine, which halogenophore carbon is coupled to at least one weak hybridization atom bearing an unsaturation, is subjected to the action of one reagent comprising at least one defined compound selected among those constituted by the association of one Bronstedt base with a defined number n of hydrofluoric acid, n being at least 3 and at most 20, advantageously 15, preferably 10. This invention is useful in organic synthesis.
