Suzuki reaction of aryl bromides and arylboronic acids is developed. The cross-coupling reactions can be performed at room temperature using 5.0 equiv. of Et3N as solvent and base without any ligands, and affording biaryl products in good yields. In addition, the chemoselecitive Suzuki reaction of bromo-N-methyliminodiacetic acid (MIDA) boronates with arylboronic acids can be achieved in this system, and
摘要 开发了一种用于钯催化芳基溴化物和芳基硼酸的 Suzuki 反应的简单温和的方案。交叉偶联反应可以在室温下使用 5.0 当量进行。Et3N 作为溶剂和碱而没有任何配体,并以良好的收率提供联芳基产物。此外,该体系还可以实现溴-N-甲基亚氨基二乙酸(MIDA)硼酸酯与芳基硼酸的化学选择性铃木反应,并通过一锅双铃木反应以中等产率制备了各种不对称三联苯。图形概要
