摘要
Peptide nanofibers decorated with palladium nanoparticles catalyzed direct coupling of aryl halides with hydroxybenzotriazole to afford the corresponding biaryls in good to excellent yields.The coupling reactions proceeded under simple,green,and mild conditions.The peptide nanofibers were used as recyclable supports in the coupling reactions.This approach is the first to use hydroxybenzotriazole as a phenylating agent.
研究了肽纳米纤维负载的Pd纳米颗粒催化卤代芳烃与羟基苯并三唑的直接偶合反应.结果表明,该偶合反应可在简单、绿色及温和的条件下进行,并可以较高产率生成相应的联芳.本文首次采用羟基苯并三唑作为苯基化试剂,且将肽纳米纤维作为一种新型可循环使用的载体,因而对现有合成方法是一个有益补充.
