Abstract: Nickel complexes are important ethylene oligomerization catalysts and have shown good application prospect in the synthesis of α-olefin due to their high activity,mild reaction conditions and high selectivity. The latest research progress of nickel complex catalysts towards ethylene oligomerization for α-olefin has been reviewed herein. In terms of molecular structure of the ligand,the discussions focus on the research status of imino pyridyl ligand nickel complex catalysts and pyrazole ligand nickel complex catalysts,including the influence of the ligand structure,substitution group effect and process conditions on the catalytic activity and product distribution. At the same time,the development of other types of ligands,including formazan,phosphine oxazoline,thiophene,dinuclear structure and dendritic ligands is also briefly introduced. The study of the effect of the fine structure of the nickel complexes on the catalytic activity and the selectivity of α-olefin has important significance for the design of high carbon α-olefin catalyst with the prospect of industrial application.

Key words: ethylene oligomerization, α-olefin, catalyst, selectivity, reactivity
