A CuI-catalyzed Suzuki cross-coupling reaction of organoboron derivatives with alkynyl bromides has been developed. In the presence of CuI (10 mol %) and 8-hydroxyquinoline (20 mol %), organoboron derivatives including aromatic and alkenyl boronic acids, potassium aryltrifluoroborates, and sodium tetraphenylborate reacted smoothly with 1-bromo-2-substituted acetylene to generate the corresponding cross-coupling
已经开发出CuI催化的有机硼衍生物与炔基溴化物的Suzuki交叉偶联反应。在CuI(10 mol%)和8-羟基喹啉(20 mol%)的存在下,有机硼衍生物(包括芳族和烯基硼酸,芳基三氟硼酸钾和四苯基硼酸钠)与1-溴-2-取代的乙炔平稳反应,生成相应的交叉偶联产物在C 2 H 5 OH中具有良好至极好的收率。重要的是要注意,芳族N,O-配体8-羟基喹啉是该反应最有效的配体。
