A green and economical electrochemical protocol has been developed to synthesize polycyclic (hetero)aromatic compounds by the [4+2] benzannulation of biaryldiazonium salts with alkynes. This protocol features a broad substrate scope. Instead of requiring diazonium reagents, these reactions can begin from anilines and can be carried out in one pot. Moreover, the readily accessible scale-up synthesis
开发了一种绿色且经济的电
化学方案,通过联芳基重氮盐与
炔烃的 [4+2] 苯并环化反应合成多环(杂)芳族化合物。该协议具有广泛的底物范围。这些反应不需要重
氮试剂,而是可以从
苯胺开始,并且可以在一锅中进行。此外,通过使用电
化学流动池实现的易于访问的放大合成证明了该协议的合成潜力。
