Twenty-three new ansa metallocene complexes of the type (C13H8-CR2-C9H6-nR′ n)ZrCl2 (38-64) (n=0, 1; R=Me, Ph, butenyl; R′=alkyl, alkenyl) and the corresponding ligand precursors have been synthesized and characterized. The bonding situation of the π-ligands to the metal of C1-bridged complexes in solution was determined by NMR-spectroscopy. All complexes were tested for catalytic ethylene polymerization after activation with methyl aluminoxane (MAO). The substituents R in the bridge and the substituents R′ in the 3-position of the indenylidene moiety have a strong influence on the activity of the catalysts and the molecular weight of the formed polymers. The ω-alkenyl substituents R and R′ allow self-immobilization of the catalysts during the polymerization.
