In this paper, an effective and selective heterogeneous catalyst was produced by immobilization of manganese and cobalt Schiff base-complexes on Co magnetite nanoparticles (MNP). The catalysts Co@SiO2[(EtO)3Si-L3]/M (M = Mn(iii) and Co(ii)) were synthesized using Co@SiO2 core-shell nanoparticles and amino-functionalized Co@SiO2. The Schiff base ligand Co@SiO2[(EtO)3Si-L3] was synthesized by reacting Co@SiO2 core-shell nanoparticles with 2-hydroxy 1-naphthaldehyde for the synthesis of Co@SiO2[(EtO)3Si-L3]/M. The catalysts were characterized by several techniques, such as FT-IR, TEM, XRD, TGA and VSM. The catalytic activities of the prepared catalysts were studied by oxidation of sulfides to the sulfoxides under different conditions. These catalysts can be easily recovered and reused in at least seven sequential cycles without considerable leaching and loss of reactivity.

A straightforward, efficient, and selective oxidation of sulfide to sulfoxide with 30% H2O2 catalyzed by copper(II)-Schiff base complex is described. The reactions proceed under mild conditions in acetonitrile at room temperature to provide a variety of aryl and alkyl sulfoxides in excellent yield.

The selective oxidation of aromatic and aliphatic organosulfides with H2O2/H2O catalyzed by metal free ammonium salts has been explored. Reactions were performed using 2.5-5 mol % of catalyst loadings, isolating the corres
