摘　　要：乙烯选择性三聚和四聚催化反应为制备1-己烯和1-辛烯提供了重要途径.在报道和披露的众多结构和组成的催化剂体系中,我们选择[PNP]配位骨架的铬催化剂体系,对其发展和应用进行了综述.论文以结构与催化性能的关联性为主线,阐述[PNP]骨架以及N和P上取代基的电子和立体空间效应对催化性能的影响.从目前的研究态势来看,[PNP]配位骨架的铬催化剂体系在乙烯选择性齐聚生产1-辛烯等线性α-烯烃方面具有发展潜力.The catalytic reaction for the selective ethylene trimerization and tetramerization provides a vital route to the production of 1-hexene and 1-octene. Among the numerous catalysts reported with diverse structures and compositions, we select the [PNP]-ligand based chromium catalysts and focus on illustration on their development and application. This contribution includes seven sections as ethylene（selective） oligomerization catalyst systems, [PNP]-ligand based Cr catalyst system, catalytic mechanism, ethylene oligomerization method, catalytic property, and conclusion and prospect, which will cover almost all of the [PNP]-ligand based Cr catalysts so far studied. In this article, we will mainly discuss the influence on the catalytic property owing to the electronic and/or steric characters of the skeleton as well as the substituents at both N and P atoms of the [PNP]-ligands. In view of the current advances in this field, this [PNP]-ligand based Cr catalyst system is of potencial in application for the production of LAO mainly as 1-octene.
