Trimerization of Ethylene to 1-Hexene with Titanium Complexes Bearing Phenoxy−Imine Ligands with Pendant Donors Combined with MAO

Abstract

New Ti complexes bearing phenoxy−imine ligands with pendant aryl−OMe donors have been developed for ethylene trimerization to produce 1-hexene. These Ti complexes combined with methylaluminoxane selectively trimerize ethylene to form 1-hexene with exceptionally high activity (e.g., 6.59 tons of 1-hexene/((g of Ti) h)) .
