Functionalized graphene oxide supported copper (I) complex as effective and recyclable nanocatalyst for one-pot three component synthesis of 1,2,3-triazoles

Abstract

Efficient, one pot three-component reaction of alkyl halides, sodium azide with terminal alkynes can be catalyzed by functionalized graphene oxide with copper(I) under thermal conditions. A series of 1,4-disubstituted 1,2,3-triazoles were obtained by this one-pot strategy. The catalyst was prepared and characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray (EDX). The catalyst can be reused at least five times without significant deactivation.
