Robust and fast oxidation of sulfides by immobilized Mo(VI) complex on magnetic nanoparticles in solvent-free condition

Abstract In this research, a heterogeneous catalyst by modifying the magnetically reusable manganese ferrite nanomaterials with oxo-peroxomolybdenum (VI) Schiff base complex was prepared. The prepared catalyst was characterized completely using different physicochemical methods. The recoverable heterogeneous catalyst was tested with different sulfides for the sulfoxidation process under solvent-free situation. The significant and superior turnover frequency (TOF) of the nanocatalyst was acquired to oxidize C7H8S compound (9408 h−1). The offered nanocatalyst has been shown catalytic selectivity, activity, and reusability in a short time. Furthermore, the heterogeneous catalyst has good recoverability at least five consecutive cycles without losing its selectivity towards products in the oxidation reaction.
