摘要：

A kind of novel star iminopyridyl ligand and the corresponding iron catalyst were prepared with 1.0 G star macromolecule, pyridine-2-carboxaldehyde and FeCl2•4H2O as raw material, and the structures were fully characterized by FT-IR, 1H-NMR, UV, ESI-MS and ICP-MS. The effects of the reaction systems and reaction conditions on catalytic properties of ethylene oligomerization were investigated. The result shows that the catalytic systems and reaction conditions have a significant effect on catalytic properties. Under the optimum reaction condition, the catalytic activity can reach up to 3.96×105 g/(mol Fe•h), and the products are mainly butene and hexene when toluene is used as solvent and MAO is used as co-catalyst. In addition, the mechanism of catalytic ethylene oligomerization was deduced on the base of the evaluation of catalytic performance of star iminopyridyl iron catalysts. © 2021, Editorial Board of Polymer Materials Science & Engineering.
