The hydroamination of electron-deficient olefins was carried out using the (CAAC)Cu–Cl (CAAC = cyclic (alkyl)(amino)carbene) catalyst with an excellent yield at room temperature and under an open atmosphere. Furthermore, the catalyst shows excellent efficiency in the hydroaryloxylation and hydroalkoxylation of alkenes under mild conditions. The efficiency of the catalyst was tested for a wide range
使用 (CAAC)Cu-Cl(CAAC = 环状(烷基)(氨基)卡宾)催化剂对缺电子烯烃进行加氢胺化,在室温和开放气氛下具有优异的收率。此外,该催化剂在温和条件下对烯烃进行加氢芳氧基化和加氢烷氧基化反应时表现出优异的效率。针对具有不同电子和空间功能的各种底物测试了催化剂的效率。已经进行了详细的计算研究以了解这些 Cu( I ) 催化反应的机理,结果表明反应通过包含铜离子的四元或六元循环过渡态进行。
