Alkyne-azide cycloaddition catalyzed by Fe-Cu nanoparticles
1,2,3-triazoles were synthesized using several alkynes and azides as starting materials in the presence of catalytic amounts of Cu-Fe nanoparticles. The process represents many advantages because it does not require additional bases or reductants, and thi
Ligand Synthesis Catalyst and Complex Metal Ion: Multicomponent Synthesis of 1,3-Bis(4-phenyl-[1,2,3]triazol-1-yl)-propan-2-ol Copper(I) Complex and Application in Copper-Catalyzed Alkyne-Azide Cycloaddition
A new bistriazole copper complex was synthesized by direct treatment of an alkyne, an azide, and CuI as copper salt through in situ ligand formation under a multicomponent reaction process. This complex was analyzed by XPS, TGA, DSC, and SEM techniques an

Catalytic activity of dithioic acid copper complexes in the alkyne-azide cycloaddition
Diverse dithioic acid copper complexes exhibit a high catalytic activity in the copper-catalyzed alkyne-azide cycloaddition using several solvents under different temperatures, showing a high efficiency with only 0.005 mmol catalyst/mmol alkyne or less. A dithioic acid copper complex derived from acetophenone was selected and used as the catalyst in the preparation of a library of 1,4-disubstituted-1,2,3-triazoles. This process occurred in high yields and good functional group tolerance.
The use of glucose as alternative reducing agent in copper-catalyzed alkyne-azide cycloaddition
1,2,3-triazoles were synthesized using several alkynes and azides as starting materials in the presence of glucose and catalytic amounts of Fehling reagent. This process is carried out under ambient pressure and temperature with good yields.

Effect of temperature on triazole and bistriazole formation through copper-catalyzed alkyne-azide cycloaddition
Temperature is an important factor in the copper catalyzed alkyne azide cycloaddition under oxidative conditions. 1,2,3-Triazoles were obtained in high yields when several alkynes and azides were reacted at methanol reflux using catalytic amounts of both
