Copper nanoparticles on activated carbon have been found to effectively catalyze the multicomponent synthesis of 1,2,3-triazoles from different azide precursors, such as organic halides, diazonium salts, anilines and epoxides in water. The first one-pot transformation of an olefin into a triazole is also described. The catalyst is easy to prepare, very versatile and reusable at a low copper loading
已发现活性炭上的铜纳米颗粒可有效催化由不同叠氮化物前体(例如水中的有机卤化物,重氮盐,苯胺和环氧化物)合成1,2,3-三唑。还描述了烯烃到三唑的第一次单锅转化。该催化剂易于制备,用途广泛且在低铜负荷下可重复使用。
