ABSTRACT:
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.
