摘　　要：苯并咪唑杂环具有良好的配位选择性,能与多种金属形成配合物.这些配合物往往具有优良的生理、荧光、催化等性能.综述了近年来含有苯并咪唑衍生物的过渡金属配合物的合成方法及其在催化乙烯齐聚和聚合方面的研究进展,并讨论了配合物的结构因素如取代基的电子效应、位阻效应等对配合物催化性能的影响规律.Benzimidazole heterocycles have good selectivity for coordination and can form a variety of metal complexes, which exhibit excellent biological, fluorescence and catalytic properties. In this paper, the progress for synthesis of benzimi-dazoles-containing transition metal complexes and their catalytic activity for ethylene oligomerization and polymerization are summarized, and the influence of the structural factor of complexes such as electronic effect and steric effect of substituent group on the catalytic performance is discussed.
