A process for obtaining vinyl compounds by dehalogenation of halofluorinated compounds having a linear, branched or cyclic structure, said halofluorinated compounds containing in the molecule at least one group: wherein Y1 and Y2, equal to or different from each other, are selected from Cl, Br, I; wherein the halofluorinated compounds are dehalogenated in the presence of a transition metal, or of transition metal couples, by operating in a biphasic system of solvents immiscible among each other, formed of a (per)fluorinated solvent and a dipolar aprotic or protic solvent (co-solvent), wherein the ratio moles co-solvent/equivalents of the halofluorinated compound ranges from 0.5 to 10, preferably from 0.5 to 5, still more preferably from 1 to 3.
