generated 1,2-oxaselenolane Se-oxide (31) in situ by a series of oxidation and [2,3]sigmatropic rearrangement steps. The remarkably active cyclic seleninate 31 proved to be the true catalyst, reacting with the thiol via a postulated mechanism in which the thioseleninate 32 is first produced, followed by further thiolysis to selenenic acid 33 and oxidation-dehydration to regenerate 31. In contrast to catalysis

Sulfoxides have been synthesised from various sulfide substrates under mild conditions exploiting CALB biocatalyst in the presence of urea hydrogen peroxide and AcOEt which acts with the dual role of solvent and reagent.
Gold(III) halides catalyze the oxidation of sulfides to sulfoxides in a phase-transferprocess. The organic sulfides, dissolved in nitromethane, are treated with (Bu4N+AuCl4−) in catalytic amount and aqueous nitric acid which acts as oxidant. The oxidation of the thio-group is selective and can be carried out also in the presence of other oxidizable groups, such as vinyl, tertiary amino, hydroxy, diol

alkyl-aryl, and diaryl sulfoxides, were readily oxidized into the corresponding sulfones, in excellent yields under mild conditions, by 2-nitrobenzene peroxysulfurintermediate yenerated in situ from 2-nitrobenzenesulfonyl chloride and potassium superoxide at −30 °C, in dry acetonitrile. Chemoselective oxidation of sulfoxides which contain both double bond and sulfinyl moiety to the sulfones, was observed
