| titleOfInvention | Vanadium complex containing aryloxy ligand and its preparation method and application |
| abstract | The invention provides a vanadium complex containing aryloxy group shown in formula (I) and a preparation method thereof. Under a nitrogen atmosphere, 2,6-dimethylphenylisocyanate or 2,6-isopropyl Phenyl isocyanate is reacted with vanadium chloride to obtain trichlorovanadimide, then reacted with (trimethylsilane) lithium methylate to obtain trialkylvanadimide, and then reacted with hydroxyl-containing ligands to obtain dialkylvanadyl imine compounds. The invention also discloses the application of the vanadium complex in the ring-opening metathesis polymerization reaction of norbornene. The invention changes the activity and thermal stability of the catalyst by changing the electron effect and steric hindrance factors of the ligand, and realizes the control of the catalyst on the ring-opening metathesis polymerization process, the molecular weight and distribution of the polymer, and the microstructure of the polymer. |
