Abstract
A catalytic composition for the dimerization, the codimerization or the oligomerization of olefins is obtained by bringing into contact at least one nickel compound that contains a heterocyclic carbene with at least one hydrocarbylaluminum halide and optionally at least one organic solvent. It is used in a process of dimerization, codimerization or oligomerization of olefins.
