Cu2O nanoparticles supported on hydrogen trititanate nanotubes (Cu2O/HTNT) catalysts have been efficiently catalyzed the multicomponent synthesis of 1,2,3‐triazoles in water at room temperature from different azide precursors, for example organic halides, sulfonates and anilines. The catalysts were synthesized by hydrothermal & wet‐impregnation methods and was characterized by HR‐TEM, EDS, XRD, XPS
负载在三钛酸氢纳米管(Cu 2 O / HTNT)催化剂上的Cu 2 O纳米粒子已在室温下有效地催化了水中的1,2,3-三唑由不同的叠氮化物前体例如有机卤化物,磺酸盐和苯胺进行多组分合成。该催化剂是通过水热湿法浸渍法合成的,并通过HR-TEM,EDS,XRD,XPS,N 2吸附脱附和ICP-MS进行了表征。该催化剂可通过离心回收并重复使用多达七个循环。通过单晶X射线衍射研究证明了1-苄基-4-(4-氯苯基)-1H-1,2,3-三唑(25)的结构。
