Barberry fruit extract assisted in situ green synthesis of Cu nanoparticles supported on a reduced graphene oxide–Fe₃O₄nanocomposite as a magnetically separable and reusable catalyst for the O-arylation of phenols with aryl halides under ligand-free conditions

Abstract

<italic>In situ</italic>synthesis of copper nanoparticles (NPs) supported on a reduced graphene oxide (RGO)–Fe₃O₄nanocomposite was carried out with barberry fruit extract as a reducing and stabilizing agent.
