By using urea linked porous organic polymers as template, a new nano palladium catalyst with low Pd loading can be easily prepared (1.0 wt% Pd only). Although such less amount of Pd was contained in this new catalyst, it is still an effective catalyst for the Suzuki-Miyaura coupling of aryl iodines and aryl boric acids, affording biphenyl products in excellent yields with outstandingly enhanced turnover numbers (up to 10,536) under green solvent (water).

尿素基多孔有机聚合物负载钯纳米粒子的简便合成及其在Suzuki-Miyaura偶联反应中的催化性能

通过使用脲连接的多孔有机聚合物作为模板,可以容易地制备具有低Pd负载的新型纳米钯催化剂(仅1.0 wt%Pd)。尽管这种新型催化剂中所含的Pd量较少,但它仍然是芳族碘和芳族硼酸的Suzuki-Miyaura偶联的有效催化剂,在以下条件下提供联苯产品,收率极高,且显着提高了周转率(最高10,536)。绿色溶剂(水)。
