A catalytic composition for the dimerization, the codimerization or the oligomerization of olefins results from the dissolution of at least one nickel complex that contains a heterocyclic carbene in a liquid mixture that comprises at least one ammonium halide or quaternary phosphonium halide, at least one aluminum halide and optionally at least one organometallic aluminum compound. It is used in a process of dimerization, codimerization or oligomerization of olefins.
