Diverse dithioicacid 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 dithioicacid copper complex derived from acetophenone was selected and used as the catalyst in the preparation of a library of 1,4-disubstituted-1

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
