copper-mediated oxidative trifluomethylation of terminal alkynes and aryl boronic acids. This method allows a wide range of functional group tolerant trifluoromethylated acetylenes and arenes to be easily prepared. After the preliminary mechanistic studies of the oxidative trifluoromethylation of terminal alkyne, an efficient copper-catalyzed oxidative trifluoromethylation of terminal alkynes and aryl boronic
三氟甲基化的乙炔和芳烃可广泛用于药物和农用化学品的合成。在2010年,我们小组报告了末端炔烃和芳基硼酸的铜介导的氧化三氟甲基化。该方法允许容易地制备宽范围的耐官能团的三氟甲基化的乙炔和芳烃。在对末端炔烃的氧化三氟甲基化进行了初步的机理研究之后,已经开发了有效的铜催化的末端炔烃和芳基硼酸的氧化三氟甲基化。通过使用注射泵将底物和一部分CF 3 TMS缓慢加入反应混合物中,成功实现了催化方案。
