摘　　要：乙烯选择性齐聚是生产高级线性α-烯烃的主要方法,具有原子经济性,符合绿色化工的发展趋势,乙烯选择性齐聚的核心在于催化剂,而催化机理研究是开发高催化活性、高选择性乙烯齐聚催化剂的关键。详细阐述了乙烯选择性齐聚反应机理方面研究的最新进展、有效的研究方法及其在乙烯选择性齐聚机理研究中的应用。提出密度泛函理论计算方法、X射线吸收精细结构(XAFS)和电子顺磁共振(EPR)等分析方法的熟练与灵活应用,可为乙烯选择性齐聚反应机理的研究提供很好的帮助,也是该领域发展的一个重要方向。Advanced linear α-olefins are mainly produced by selective oligomerization of ethylene. Benefiting from the atom economy,selective oligomerization is in accord with the development tendency of green chemistry. Catalyst is the core of selective oligomerization and the catalytic mechanism is the key for developing the catalyst with high activity and selectivity. Recent development of the mechanism for ethylene oligomerization,efficientive research method and their application are reviewed in detail. The skilled and flexible application of density functional theory and the spectrometry such as X-ray absorption fine structure（XAFS） and electron paramagnetic resonance（EPR） is quite helpful for the ethylene oligomerization mechanism,which is an important research field in the future.
