金属树枝状大分子催化剂在均相催化中的应用

Application of Metallodendrimer Catalysts in Homogeneous Catalysis

简要介绍了金属树枝状大分子催化剂的几种常见合成方法,重点论述了这类催化剂在加氢、氢甲酰化、C—C耦合、烯烃聚合及其他均相催化反应中的应用。金属树枝状大分子催化剂结合了均相和多相催化剂的优点,对许多均相反应具有较高活性和选择性。作为均相催化剂使用后容易从反应体系中分离出来,可以循环使用,具有广阔的应用前景。

Some common synthetic methods of metallodendrimer catalysts were briefly introduced,applications of the above catalysts for hydrogenation, hydroformylation, C - C coupling reaction, olefin polymerization and other homogeneous catalytic reactions were emphatically reviewed. The metallodendrimer catalysts combine the advantages of homogeneous catalysts and heterogeneous catalysts, and have higher activity and selectivity for many homogeneous reactions. As a homogeneous can be recycled. This kind of catalysts have wide catalyst, it is easily separated from the reaction system and application prospects.
