Abstract: Disclosed is a process for prepararing bridged Group 4 metal complexes containing a neutral diene ligand starting from the corresponding novel, metal diene containing complexes by reaction thereof with the divalent derivative of a bridged bidentate ligand compound. The novel, intermediate metal diene complexes, their formation from tetravalent metal salts and an integrated process combining both process steps are claimed.

Abstract: Group 4 metal complexes comprising an indenyl group substituted in the 2 or 3 position with at least one group selected from hydrocarbyl, perfluoro substituted hydrocarbyl, silyl, germyl and mixtures thereof, said indenyl group further being covalently bonded to the metal by means of a divalent ligand group, catalytic derivatives thereof and their use as olefin polymerization catalysts are disclosed.
