A decarboxylative coupling reaction for alkynyl carboxylic acids and arylsiloxanes was developed using a palladium catalyst. This method provided the desired coupled products in moderate to good yields by reacting the alkynyl carboxylic acids and arylsiloxanes with Pd(dba)2 (1.0 mol %), 1,1-bis(diphenylphosphino)methane (1.0 mol %), and AgF2 (2.0 equiv) at 60 °C for 6 h.
使用钯催化剂开发了炔基羧酸和芳基硅氧烷的脱羧偶联反应。通过使炔基羧酸和芳基硅氧烷与Pd(dba)2(1.0 mol%),1,1-双(二苯基膦基)甲烷(1.0 mol%)和AgF 2反应,该方法以中等至良好的产率提供了所需的偶联产物。(2.0当量)在60°C下放置6小时。
