been developed using 2,2′‐azobisisobutyronitrile (AIBN) as traceless cyanating agent. The non‐toxic and readily available AIBN was used for the carbonylative cyclization of benzamides via copper catalysis. The method is also applicable for the regioselective cyanation of furan, benzofuran, thiophene, benzothiophene, and pyrrole carboxamide derivatives.
使用2,2'-偶氮二异丁腈(AIBN)作为无痕量氰化剂,已经开发出了一种高效的铜催化的苯甲酰胺区域选择性CH键羰基化反应。无毒且易于获得的AIBN通过铜催化作用用于苯甲酰胺的羰基化环化反应。该方法也适用于呋喃,苯并呋喃,噻吩,苯并噻吩和吡咯甲酰胺衍生物的区域选择性氰化。
