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 paper describes the synthesis and structural characterization of four novel copper(I) complexes [CuL(PPh3)2] (L = 3-hydroxy-3-(p-R-phenyl)-2-propenedithioate). In addition, a tautomeric equilibrium in solution was found and Hammett correlations with 13C NMR parameters were studied. The structure of one complex was fully established by X-ray diffraction analysis.
