The carbonylative Suzuki cross-coupling reaction of arylboronic acid with aryl and heteroaryl iodides using polymer supported palladium-N-heterocyclic carbene complex (PS-Pd-NHC) as an efficient heterogeneous, recyclable catalyst is described. The developed catalytic system is found to be effective for the carbonylative coupling reaction of aryl, heteroaryl, and bicyclic heteroaryl iodides (5-iodoindole
描述了使用聚合物负载的钯-N-杂环卡宾配合物(PS-Pd-NHC)作为有效的多相可循环催化剂,芳基硼酸与芳基和杂芳基碘化物进行羰基化Suzuki偶联反应。发现开发的催化体系对于芳基,杂芳基和双环杂芳基碘化物(5-碘吲哚和3-碘喹啉)与各种芳基硼酸衍生物的羰基化偶联反应有效,从而提供了所需产品的良好或优异的收率。由于催化剂的易于处理和简单的后处理程序,并且对环境有益且催化剂有效地可回收,该方案是有利的。 联芳基酮-硼-多相催化-钯-铃木羰基化
