The invention provides a preparation method of chloridized 2-n-propionyl-1,10-phenanthroline (amine) Fe (II) complex shown in formula (I) and application of the complex used as an ethylene oligomerization catalyst. The variables in formula (I) are defined in instruction. The method comprises the following steps: firstly, 2-n-propionyl-1,10-phenanthorine is prepared from 1,10-phenanthorine and raw material tri-n-propylaluminium by hydrolysis and oxidizing reaction with nitrobenzene. Secondly, 2-n-propionyl-1,10-phenanthroline (amine) ligand is obtained from 2-n-propionyl-1, 10-phenanthorine and the substituted aniline by condensation. Thirdly, a targeting product is obtained by the reaction of ligand with ferrous chloride. The synthetic method has the advantages that the method has few steps and simple process, is low in cost, takes non-toxic tri-n-propylaluminium to replace potassium cyanide in the conventional method and has broad prospect in industrialization. |
