Copper-polymer nanocomposite: An efficient catalyst for green Huisgen click synthesis.

A new method for Huisgen [3+2] cycloaddition synthesis of 1,4- and 1,4,5-substituted-1 H -1,2,3-triazoles was reported. The reaction was catalyzed by the product of thermolysis of copper (II) poly-5-vinyltetrazolate. Heterogeneous catalyst includes copper nanoparticles which supported on polymeric matrix. It presents recovered and recycled catalyst and the catalyzed reaction proceeds in aerobic conditions at room temperature in aqueous media. [ABSTRACT FROM AUTHOR]
