Synthesis and Characterization of Copper(I)‐Cysteine Complex Supported on Magnetic Layered Double Hydroxide as an Efficient and Recyclable Catalyst System for Click Chemistry Using Choline Azide as Reagent and Reaction Medium

Abstract

In this study, Fe3O4@LDH@cysteine–Cu(I) nanoparticles as a novel and recyclable catalytic system was designed and successfully synthesized. These nanoparticles show high catalytic activity for preparation of the triazole family through reaction of the organic halides with alkynes in the presence of choline azide as reagent and reaction medium. In addition, Fe3O4@LDH@cysteine–Cu(I) could be easily recovered and reused for five times without any significant loss in catalytic activity.
