Bis(enamido) ligand for polymerization catalysts |
| 초록 |
Dianion ligand, dipotassium bis(enamido) compound can be easily generated by deprotonation raction with KH from a alpha-diimine compound, which successfully serves as a ligand for nickel-based polymerization catalyst. Some early transition metal complexes have been successfully synthesized from the dianion ligand. The complexes are chracterestic in that they have electron-rich methylene carbons in the ligand frame. Interaction with Lewis acidic cocatalyst can afford zwitterionic active species or doubly activated dicationic active species. Synthesis of the complexe, the activation reaction with cocatalyst as MAO, B(C6F5)3 or Al(C6F5)3, and ethylene polymerization reactivities will be disclosed. |
