Summary:In order to carry out selective dimerization of propylene principally into branched dimers, a catalytic composition resulting from at least partly dissolving a nickel compound mixed or complexed with a tertiary phosphine carrying a functional group is used in a medium resulting from mixing at least one quaternary ammonium halide and/or at least one quaternary phosphonium halide, at least one aluminum halide and optionally at least one organometallic aluminum compound.
