Hexahydrocyclopenta[e]-as-indacen-1-yl and octahydrobenzo[e]-as-indacen-1-yl based catalyst complexes and process for use thereof

Abstract

This invention relates to hexahydrocyclopenta[e]-as-indacen-1-yl and octahydrobenzo[e]-as-indacen-1-yl based catalyst complexes represented by the formula:TLAMXwherein: M is a group 3-6 metal; n is the oxidation state of M; A is a substituted or unsubstituted polycyclic arenyl ligand bonded to M wherein the polycyclic ligand contains an indenyl fragment with two partially unsaturated rings annulated to the phenyl ring of the indenyl ligand fragment; L is a substituted or unsubstituted monocyclic or polycyclic arenyl ligand bonded to M, or a substituted or unsubstituted monocyclic or polycyclic heteroarenyl ligand bonded to M, or is represented by the formula JR'where J is a group 15 or 16 heteroatom bonded to M, R′ is a substituted or unsubstituted hydrocarbyl substituent bonded to J, and z is 1 or 2; T is a bridging group; y is 1 or 0; and each X is independently a univalent anionic ligand, or two Xs are joined and bound to the metal atom to form a metallocycle ring, or two Xs are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand.
