An expeditious protocol for the one-pot synthesis of 1,4-disubstituted (β-hydroxy)-1,2,3-triazoles in an aqueous medium has been developed using copper aluminate nanoparticles. This heterogeneous catalytic system was found to drive a multicomponent click reaction between organic azides (generated in situ from epoxides or halides) and terminal aliphatic or aromatic alkynes in up to 96% yield without
使用铝酸铜纳米粒子开发了一种在水性介质中一锅合成 1,4-二取代 (β-羟基)-1,2,3-三唑的快速方案。发现这种多相催化系统可以在不需要还原剂的情况下以高达 96% 的产率驱动有机叠氮化物(由环氧化物或卤化物原位生成)和末端脂肪族或芳香族炔烃之间的多组分点击反应。合成了结构多样的 1,2,3-三唑,收率非常好,催化剂可以通过简单的过滤轻松分离、回收和在六个后续循环中重复使用。
