Cuprous oxide on charcoal (Cu2O/C), the preparation of which is described for the first time, catalyzes the formation of 1,4-disubstituted 1,2,3-triazoles from organic azides and terminalalkynes in good to excellent yields (69-94%). These disubstituted triazoles can be equally efficiently generated in a one-pot process from alkyl bromides, sodiumazide, and terminal acetylenes in 50% aqueous isopropanol

A novel and highly efficient method for the synthesis of 1,4‐disubstituted‐1H‐1,2,3‐triazoles by copper‐catalyzed azide‐alkyne cycloaddition has been developed. This economic and sustainable protocol uses a readily available Benedict's solution/Vitamin C catalyst system affording a wide range of 1,4‐disubstituted‐1H‐1,2,3‐triazoles under mild conditions.
supported Cu (Cu/PANI) catalyst served as an efficient heterogeneouscatalyst for the regioselective synthesis of 1,4-disubstituted-1H-1,2,3-triazoles via click chemistry approach. Herein, we have illustrated the development of two copper based heterogeneouscatalysts using PANI as solid support through interfacial polymerization method. The catalysts can be easily recycled and reused resulting excellent
聚苯胺(PANI)负载的Cu(Cu / PANI)催化剂可作为有效的非均相催化剂,用于通过点击化学方法区域选择性合成1,4-二取代-1 H -1,2,3-三唑。在本文中,我们通过界面聚合方法说明了使用PANI作为固体载体的两种铜基非均相催化剂的开发。该催化剂可以容易地再循环和再利用,从而产生了极佳的三唑产率。该方案的主要优点是易于制备,催化剂的多相性质,使用水作为助溶剂和室温反应条件。在本文中,已经描述了使用我们开发的Cu-PANI催化剂合成1 H -1,2,3-三唑的三种不同方案。

Cu(I)‐AMPS was found to be highly active in the CuAAC reaction of various organic azides with alkynes affording the corresponding 1,4‐disubstituted 1,2,3‐triazoles in a regioselective manner in air at room temperature and usingwater as solvent. The insolubility and/or partial solubility of the organic azide and alkyne precursors as well as the heterogeneous Cu(I)‐AMPS catalytic system points
