A new paradigm of copper oxide nanoparticles catalyzed reactions: synthesis of 1,2,3-triazoles through oxidative azide-olefin cycloaddition

Abstract

Oxidative [3 + 2] cycloaddition of activated olefins and azides is reported with readily available CuO nanoparticles. 1,4-Disubsitituted and 1,4,5-trisubstituted 1,2,3-triazoles have been achieved without use of base or additives in a shorter time.
