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.
已制备出三齿SNS配体的Cr(III)配合物，并将其评估为乙烯三聚反应的催化剂，其中几种配合物在用甲基铝氧烷活化后，对1-己烯具有非常高的活性和优异的选择性。这些新配合物展示了早期过渡金属上硫基配体在催化方面的潜力。
