Abstract

A copper complex containing decavanadate nanocluster, Na-2[Cu(H2O)(6)](V10O28]center dot 4H(2)O, was prepared by reaction of Cu(NO3)(2)center dot 4H(2)O and NH4VO3 in an aqueous solution at pH = 4 and its structure was characterized using IR, CV and X-ray crystallography. It was found to be a highly efficient and effective catalyst for the azide alkyne cycloaddition and one-pot three-component (A(3)) coupling of aldehydes, amines, and alkynes to produce 1,2,3-triazoles and propargylamines respectively in high yields without any co-catalyst or activator.
