摘要：

A regioselective and tunable synthesis of 1,5-disubstituted 1,2,3-triazloles from oxidative and eliminative [3+2] cycloadditions of nitroolefins and organic azides under solvent-free condition in the presence and absence of commercially available CuO nanoparticle catalyst is described. In the presence of the catalyst under solvent-free condition, nitro group is retained in the product while it gets eliminated in the absence of the catalyst. (C) 2016 Elsevier Ltd.
