A catalyst composition for use in dimerizing, co-dimerizing or oligomerizing olefins comprises:

    • at least one zero-valent nickel complex;
    • at least one acid with formula H+X- in which X- represents an anion;
    • and at least one ionic liquid with general formula Q+ A- in which A- is an anion identical to or different from X-.
    • The composition can also comprise a nitrogen-containing ligand. It can be used in dimerizing, co-dimerizing, oligomerizing and in polymerizing olefins.
