Schiff base complex coated Fe3O4 nanoparticles: A highly reusable nanocatalyst for the selective oxidation of sulfides and oxidative coupling of thiols

In this work, a new nanomagnetic complex of Cu(II) has been synthesized. The prepared catalyst was characterized by TG/DTG, FT-IR, TEM, VSM, ICP, AAS, XRD, EDS and SEM analyses. It was found to be an efficient catalyst for the oxidation of sulfides and oxidative coupling of thiols. High catalytic activity, ease of recovery from the reaction mixture using an external magnet, and several reuse times without significant losses in performance are additional eco-friendly attributes of this catalytic system.
