Abstract

A novel Fe3O4@VO (salen) complex was designed as an efficient and heterogeneous catalyst for selective oxidation of sulfides to sulfoxides using H2O2 at room temperature. The catalyst was characterized by techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis, Fourier-transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), vibrating-sample magnetometry (VSM), and inductively coupled plasma optical emission spectrometry (ICP-OES) analysis. The simple preparation of the catalyst from commercially available materials, excellent chemoselectivity, easy separation of products, and straightforward recovery and reusability of the catalyst with unaltered activity make our procedure a green and practical method.
