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）。
