Synthesis of copper containing polyaniline composites through interfacial polymerisation: An effective catalyst for Click reaction at room temperature

Polyaniline (PANI) supported Cu (Cu/PANI) catalyst served as an efficient heterogeneous catalyst for the regioselective synthesis of 1,4-disubstituted-1H-1,2,3-triazoles via click chemistry approach. Herein, we have illustrated the development of two copper based heterogeneous catalysts using PANI as solid support through interfacial polymerization method. The catalysts can be easily recycled and reused resulting excellent yields of the triazoles. The main advantages of the protocol are ease of preparation, heterogeneous nature of the catalysts, use of water as a co-solvent and room temperature reaction conditions. In this paper, three different protocols have been described for the synthesis of 1H-1,2,3-triazoles using our developed Cu-PANI catalysts. (c) 2021 Elsevier B.V. All rights reserved.
