Palladium-catalyzed Suzuki–Miyaura cross-coupling reaction of potassium pyridine-2-trifluoroborates and various aryl (heteroaryl) halides can generate the corresponding desired coupling products with moderate to good yields. It can be carried out under the conditions with ethanol as solvent, Pd(OAc)2 and SPhos as catalyst system and Na2CO3 as a base.
吡啶-2-三氟硼酸钾与各种芳基(杂芳基)卤化物的钯催化的Suzuki-Miyaura交叉偶联反应可以产生相应的所需偶联产物,产率中等至良好。可以在以下条件下进行:乙醇为溶剂,Pd(OAc)2和SPhos为催化剂体系,Na 2 CO 3为碱。
