摘要
A new solid system based on montmorillonite supported oxone has been developed and used for the oxidation of thiomannoside. The oxidation properties of oxone immobilized on montmorillonite were affected by polarity of the solvent, resulting in the different sulfoxide to sulfone ratios as the products. Toluene was the only solvent favouring sulfone formation over sulfoxide. X-ray crystal structures of the starting compound as well as the corresponding sulfoxide (major epimer Rs) and sulfone are also reported.
