catalysts for Suzuki–Miyaura reactions. Reactions of aryl halides with various boronic acids in the presence of different bases and solvents including organic polar, non-polar and water as sole solvent without the aid of phase-transfer catalysts, under phosphine-free and aerobic conditions have been studied. Especially, deactivated aryl bromides and activated aryl chlorides afforded good isolated yields
我们报道了使用稳定在两亲性葡萄糖衍生碳球上的钯纳米颗粒作为铃木-宫浦反应的非均相催化剂。在不同的碱和溶剂包括有机极性的,非极性和水作为唯一的溶剂没有相转移催化剂的助剂的存在各种硼酸,膦下芳基卤化物的反应,-游离和需氧条件进行了研究。特别是,失活的芳基溴化物和活化的芳基氯化物在纯水中提供了良好的分离产率。催化剂可重复使用多达四个循环,而活性没有任何明显的损失。
