q
complex comprising a bis-arylimine pyridine ligand and M is a transition metal atom; n matches the formal oxidation state of the transition metal atom M; X is halide, optionally substituted hydrocarbyl, alkoxide, amide, or hydride; NC− is a non-coordinating anion; and p+q matches the formal oxidation state of the transition metal atom M. The transition metal complexes of the present invention, their complexes with non-coordinating anions and catalyst systems containing such complexes have good solubility in non-polar media and chemically inert non-polar solvents especially aromatic hydrocarbon solvents. The catalyst systems can be used for a wide range of (co-)oligomerization, polymerization and dimerization reactions.
