Paragraph 0071-0075, (2020/11/23)
The invention relates to a phenoxy imine substituted ruthenium complex as well as preparation and application thereof, and the chemical general formula of the ruthenium complex is shown in the specification, in the formula, R1 is C1-C20 alkyl with a linear, branched or cyclic structure, or C7-C30 mono-or polyaryl substituted alkyl; R2 - R5 are respectively and independently hydrogen, or nitro, orC1-C20 straight-chain and branched-chain alkyl, or C7-C30 monoaryl or polyaryl substituted alkyl, or C6-C18 aryl, or halogen. Compared with the prior art, the method has the advantages that the effectof double-component catalysis can be achieved, polymerization starting can be effectively controlled, industrial operation is facilitated. Meanwhile, the catalyst has the advantages of being resistant to water, oxygen and impurities. In addition, phenoxy imine ligands are easy to synthesize, steric hindrance and the electronic effect of ligand substituents are easy to adjust, and the method is suitable for industrial production. The catalytic activity of ruthenium in a metal center can be effectively regulated and controlled, so that the catalyst is effectively regulated and controlled.
