Transition-metal-catalyzed lactamization and lactonization of C–H bonds with CO2 assisted by the chelation of amino or hydroxyl groups have been developed but limited to the use of precious metal catalysts such as palladium and rhodium. In this work, we report the nonprecious metal nickel-catalyzed lactamization reaction of 2-arylanilines with CO2 under redox-neutral conditions via C–H bond activation
过渡金属催化的内酰胺化以及C-H键与CO 2在氨基或羟基螯合辅助下的内酯化已经得到发展,但仅限于使用贵金属催化剂,例如钯和铑。在这项工作中,我们报道了在氧化还原中性条件下通过C-H键活化发生的非贵金属镍催化的2-芳基苯胺与CO 2的内酰胺化反应。该反应表现出优异的官能团耐受性,以中等到高产率提供各种菲啶酮。
