An electrochemical synthesis of N-acylbenzotriazoles has been developed under mild conditions with good to excellent yields using aldehydes and benzotriazole as starting materials. In addition, a one-pot reaction of aldehyde, benzotriazole and phenol has been achieved affording phenolic esters in moderate yields under the combination of electricity-on/off conditions, where N-acyl benzotriazole acted
以醛类和苯并三唑为原料,在温和条件下开发了一种电化学合成N-酰基苯并三唑,收率良好至优异。此外,已经实现了醛、苯并三唑和苯酚的一锅反应,在通电/断电组合条件下以中等收率提供酚酯,其中N-酰基苯并三唑作为良性酰化试剂。值得注意的是,该研究提供了环境友好的合成方法,因为不需要超化学计量的危险化学氧化剂,避免了腐蚀性/有毒试剂,并且显着减少了废物产生。电化学合成的关键是邻苯二甲酰亚胺氧化苯并三唑醛加合物N -oxy (PINO),由N-羟基邻苯二甲酰亚胺 (NHPI) 作为氧化还原介质生成。
