Cu(I)@Isatin-Glycine-Boehmite nanoparticles: as novel heterogeneous catalyst for the synthesis and selective oxidation of sulfides

Abstract

This work present the synthesis of Cu (I) immobilized on modified boehmite nanoparticles as an environmentally friendly heterogeneous catalyst for the synthesis of sulfides and their oxidation to the corresponding sulfoxides in good to excellent yields. The structure of the catalyst was studied by scanning electron microscopy, X-ray diffraction, thermogravimetric, inductively coupled plasma atomic emission spectroscopy, and Brunauer–Emmett–Teller techniques. The use of this heterogeneous nanocatalyst in mentioned organic reactions allowed achieving good results such as the excellent stability, high efficiency, low cost, easy recovery, and reusability of catalyst for four continuous cycles.
