A polystyrene-supported Pd complex bearing a cyclic pyridine-2,6-bisiamide ligand was synthesized and its catalytic activity in the Suzuki–Miyaura coupling reaction of 2,6-bromopyridine with 4-methoxyphenylboronic acid in aqueous media was investigated. The solid-supported catalyst exhibited catalytic activity and chemoselectivity that were comparable to those of homogeneous catalyst. The reusability of the solid-supported catalyst was also examined.

聚苯乙烯负载的含Pd（II）的大环配合物的合成，作为可重复使用的化学选择性Suzuki-Miyaura偶联反应的催化剂

合成了带有环吡啶-2,6-双二酰胺配体的聚苯乙烯负载的钯配合物，并研究了其在水介质中2,6-溴吡啶与4-甲氧基苯基硼酸的Suzuki-Miyaura偶联反应中的催化活性。固体负载的催化剂表现出与均相催化剂相当的催化活性和化学选择性。还检查了固体负载催化剂的可重复使用性。
