新型配位型含噻吩基三氯一茂钛的合成及其催化乙烯三聚反应的研究
Ethylene Trimerization with Half-sandwich Titanium Complexes bearing a Pendant Thienyl Group
本文合成了一组未见报道的新型含噻吩基三氯一茂钛络合物，并对其进行了1H NMR , MS, IR and EA等结构表征。在甲基铝氧烷（MAO）作用下，发现它们可以催化乙烯三聚，并且具有很高的催化活性和1－己烯选择性。硫原子对中心金属的配位是产生三聚催化活性的重要原因。本文对不同条件下的催化性能进行了讨论。
new series of half-sandwich titanium complex with a pendant thienyl group were synthesized and characterized by 1H NMR , MS, IR and EA. Activated by methylalumoxane (MAO), they can trimerize ethylene to 1-hexene with considerable activity and high selectivity. The coodination of the sulfur atom to the titanium center is proposed to be responsible for the selective trimerization of ethylene. Their catalytic behavior under different conditions is discussed.
