The invention belongs to the field of chemical synthesis of organic metal materials, and discloses an imidazoline-modified iron metal complex and a preparation method and application thereof, comprising the following steps: adding paraformaldehyde into a saturated acid solution, and then adding salicylaldehyde to react to prepare Intermediate product 1, the intermediate product 1 is reacted with imidazole compounds and aniline successively to obtain imidazoline modified functional ligands, and then reacts with iron metal salts in a solvent to obtain imidazoline modified iron metal complexes. The iron-based imidazoline functional complex prepared by the invention has high catalytic performance and reuse when catalyzing the hydrosilylation reaction between silane and compound containing double bonds, and the reaction conversion rate can reach up to 76%. All have high reaction conversion rate and will not convert olefins in the chain, and have excellent reaction selectivity. The invention has the characteristics of simple operation, obvious effect, low cost, recyclable catalyst and no pollution to products, and has high research value and application prospect. |
