Highly dispersed palladium chloride catalysts locked in triphenylphosphine-functionalized knitting aryl network polymers (KAPs) are developed and exhibit excellent activity under mild conditions in the Suzuki-Miyaura cross-coupling reactions of aryl chlorides in aqueous media. This work highlights that the microporous polymers not only play the role of support materials, but also protect the Pd species from aggregation and precipitation, hence, positively effect the catalysis activity.
高度分散的氯化钯催化剂被锁定在三苯基膦功能化的编织芳基网络聚合物（KAPs）中，在温和条件下，在水相介质中的芳基氯的Suzuki-Miyaura 交叉偶联反应中表现出优异的活性。这项工作强调了微孔聚合物不仅起到了支撑材料的作用，而且还防止了 Pd 物种的聚集和沉淀，从而对催化活性产生了积极的影响。
