A new polymer-supported hypervalent iodine reagent, polystyrene-supported iodosylbenzene sulfate (PS-IBS), can be conveniently prepared by the reaction of polystyrene-supported (diacetoxyiodo) benzene (PS-DIB) with sodium bisulfate monohydrate under solvent-free conditions. This new recyclable reagent effects clean and efficient oxidation of a wide range of alcohols and sulfides to the corresponding carbonyl compounds or sulfoxides in high conversions under mild conditions. The final products are conveniently separated from the polymeric byproduct by simple filtration and isolated in good purity after evaporation of solvent. Recycling of the resin is possible with minimal loss of activity after several reoxidations.
