Abstract

The selective oxidation of sulphide to sulfoxide is an important transformation process in the industry. In this work, a novel polyaniline-supported iron catalyst (Fe@PANI) was designed and synthesised for catalyzing the reaction. It was found that the material exhibited magnetism and could be recycled by magnetic separation and reused without deactivation. The magnetic Fe@PANI-catalyzed oxidation reaction of sulphides could selectively form sulfoxides without the generation of sulfones. The inexpensive catalyst and mild and green conditions make the reaction practical for large-scale applications.
