A new trimerization system for ethene consisting of CrCl3(thf)3, a novel aminophosphane ligand, and Et3Al was developed, showing very promising results in selectivity and applicability (see picture). Investigations on organometallic model compounds give an indication of the nature of the active catalyst species.
