Abstract
Ethylene is trimerized to form 1-hexene by using a catalyst comprising an aluminoxane and polydentate phosphine, arsine, and/or stibine coordination complex of a chromium salt. Catalysts, complexes, and ligands enabling production of 1-hexene in extremely high yields and purity are also described.
