Catalyst systems that have a benzoindenoindolyl ligand are disclosed. The catalysts are useful for olefin polymerizations. They have high activity and are less susceptible to decreased activity with changes in activator level or changes in polymerization temperature. The resultant polymers have low polydispersity. A new method of preparing N-alkyldihydroindenoindoles is also disclosed. N-alkyldihydroindenoindoles are useful precursors for the benzoindenoindolyl ligand.
