Catalyst systems useful for oligomerizing or polymerizing olefins are disclosed. The catalyst systems comprise an activator and an organometallic complex. The complex includes a late transition metal (Group 8 to 10) and an aromatic 1,2-diimine ligand chelated to the metal. The diimine ligands are easily made using Schiff base chemistry from readily available aromatic 1,2-diamines and an aldehyde or ketone. |
