Abstract
Catalyst systems for the oligomerization and/or isomerization of olefins which comprise a nickel (II) complex and a co-catalyst. The nickel (II) complex is a square planar species with a trivalent Group V donor ligand, preferably a phosphine or phosphite ligand, a halogen or pseudo-halogen ligand and a bidentate dithio ligand, especially a substituted dithio-.beta.-diketone ligand.
Claims11
In a catalyst system for the oligomerization and/or isomerization of olefins which comprises a nickel (II) complex and co-catalyst, the improvement wherein the nickel (II) complex is a square planar species with a trivalent Group V donor ligand, a halogen or pseudo-halogen ligand and a dithio-.beta.-diketone ligand which may be substituted with one or more non-deleterious groups.
