Cr(III) complexes of tridentate SNS ligands have been prepared and evaluated as catalysts for ethylene trimerization, with several giving very high activity and excellent selectivity toward 1-hexene when activated with methylaluminoxane. The new complexes illustrate the potential of sulfur-based ligands on early transition metals for catalysis.
三齿 SNS 配体的 Cr(III) 配合物已被制备并评估为乙烯三聚的催化剂,当用甲基铝氧烷活化时,其中几种具有非常高的活性和对 1-己烯的优异选择性。新的配合物说明了硫基配体对早期过渡金属催化的潜力。
