Synthesis of bi-aryls via a domino Pd-catalyzed reaction of 1-(2-bromophenyl)-2-methylpropan-1-ones/(2-bromophenyl)(cyclohexyl)methanones is presented. The mechanism of the reaction is believed to proceed through a five membered palladacycle that combines with a second molecule of halo-arene to yield the bi-aryls. This method is quite successful to deliver highly sterically crowded bi-aryls with dense
提出了通过多米诺骨牌催化的1-(2-溴苯基)-2-甲基丙烷-1-酮/(2-溴苯基)(环己基)甲酮反应合成联芳基。据认为,反应机理是通过五元的palladacycle来进行的,该五元的palladacycle与卤代芳烃的第二个分子结合以生成联芳基。该方法非常成功地在芳香环上提供了空间密集的,具有致密官能团的联芳基。
