We report the direct amidation of arene C-H bonds using sulfonyl azides as the amino source to release N(2) as the single byproduct. The reaction is catalyzed by a cationic rhodium complex under external oxidant-free conditions in the atmospheric environment. A broad range of chelate group-containing arenes are selectively amidated with excellent functional group tolerance, thus opening a new avenue
我们报告使用磺酰叠氮化物作为氨基源释放 N(2) 作为单一副产品的芳烃 CH 键的直接酰胺化。该反应在大气环境中的外部无氧化剂条件下由阳离子铑络合物催化。广泛的含螯合基团的芳烃被选择性酰胺化,具有优异的官能团耐受性,从而为实际分子间 CN 键的形成开辟了新途径。
