Abstract: A copper complex anchored on functionalized Fe₃O₄ nanoparticles was prepared by a simple and inexpensive procedure using commercially available materials. The prepared catalyst was characterized by a range of physical and spectroscopic techniques. Ease of operation, high efficiency, eco-friendly procedure, easy separation of the catalyst and reusability for several consecutive runs without significant loss of its activity are several advantages of this catalyst. The catalytic activity has been explored for the oxidation of sulfides, oxidative coupling of thiols and synthesis of 5-substituted tetrazoles.
