Abstract
|
A novel magnetic nanoparticle was synthesized with effective catalytic properties and recyclable ability. This heterogeneous nanocatalyst was identified using Fourier transform infrared, scanning electron microscopies, X-ray diffraction, vibrating sample magnetometer, inductively coupled plasma atomic emission spectroscopy and thermogravimetric analysis methods. The nanocatalyst was used for the syn- thesis of the one-pot CAS coupling synthesis of sulfide in the presence of KOH, S8 as the sulfur source in DMSO as the solvent at 100 C. Also, the oxidation of sulfides to sulfoxides and oxidative coupling of thi- ols to disulfides in the presence of the catalyst was tested. The catalyst has unique properties such as abil- ity of magnetic separation from the reaction, high repeatability, and high thermal and chemical stability. 2018 Published by Elsevier Ltd.
