palladium-catalyzed Suzuki coupling of aromatic triazine esters with arylboronic acids has been developed. The reaction proceeds smoothly in toluene at 110 °C using 2 mol% of MCM-41-bound bidentate phosphine palladium complex [MCM-41-2P-Pd(OAc)2] as catalyst and provides a novel and practical method for the synthesis of aryl ketones starting from readily available aromatic acids in a one-pot procedure with
摘要 已经开发出一种高效的多相钯催化的芳族三嗪酯与芳基硼酸的 Suzuki 偶联。以 2 mol% 的 MCM-41 键合二齿膦钯配合物 [MCM-41-2P-Pd(OAc) 2 ] 为催化剂,反应在 110 ℃的甲苯中顺利进行,为合成芳基酮从容易获得的芳香酸开始,在一锅法中以中等至极好的收率。MCM-41-2P-Pd(OAc) 2催化剂可重复使用至少七次,其催化活性没有任何明显降低。
