Abstract The oxidation of organiccompounds by potassium permanganate supported on Montmorillonite K10 has been studied under solvent‐free conditions and the results compared with those from corresponding reactions where the reductants are dissolved in methylene chloride. Under both sets of conditions, primary benzylic and secondary alcohols are converted to aldehydes and ketones respectively, sulfides

TiCl4 proved to be a highly reactive reagent system for the desulfurization of thioamide and thioketone derivatives in excellent yields and short reaction times with high purity. Sulfides were also found to undergo oxidation to sulfones under similar reaction conditions. In most cases, these reactions are highly selective, simple, and clean, affording products in high yields and purity.
Aromatic and aliphatic sulfides are readily oxidized to sulfoxides or sulfones in high yield with 35% hydrogen peroxide in the presence of cyanuric chloride (CC) as an efficient activator. The oxidation of sulfides proceeds at room temperature and the corresponding sulfoxides or sulfones was selectively obtained by controlling the amounts of H2O2 and CC.

AbstractA mild, efficient, and highly selective oxidation method of sulfides to sulfoxides using Fe(NO3)3·9H2O and catalyticamounts of KBr or NaBr in the presence of wet SiO2 (50% w/w) has been developed. A variety of aliphatic and aromatic sulfides were selectively oxidized at room temperature in good to excellent yields. Graphical abstract
Cellulose supported manganesedioxide nanosheets, as a heterogeneous bio-supported and green catalyst, were synthesized by soaking porous cellulose in a potassium permanganate solution. The prepared catalyst was used effectively for the oxidation of various types of alkyl arenes, alcohols and sulfides to their corresponding carbonyl and sulfoxide compounds, respectively in high yields using air as
