| titleOfInvention | Tetradentate nitrogen-oxygen symmetric ligand containing chiral cyclohexanediamine and preparation method and application thereof |
| abstract | The invention discloses a tetradentate nitroxide symmetric ligand containing chiral cyclohexanediamine and a preparation method and application thereof. The invention provides a tetradentate nitroxide symmetric ligand containing chiral cyclohexanediamine, which has a similar structure with a classical salen ligand, can be subjected to tetradentate coordination of N, N, O, O and is complexed with alkyl aluminum to form a complex. The ligand of the invention has special structure and simple preparation method, the formed aluminum complex can be used as a catalyst for ring-opening polymerization of cyclic lactone, the catalytic activity is high, the stereoselectivity is high, the reaction rate is high, the polymerization operation is simple, products with different molecular weights can be obtained in a controllable manner, the selectivity is wide, and the market prospect is good. |
