Selective Oxidation of Bulky Sulfides to Sulfoxides over Titanosilicates Having an MWW Structure in the Presence of H2O2 under Organic Solvent-Free Conditions.

Abstract A selective hydrogen peroxide oxidation of sulfides to sulfoxides using Ti-MWW and Ti-IEZ-MWW catalysts was developed. This reaction was carried out under organic solvent-free conditions, and the only side-product was water. Improvement of catalytic activity toward bulky sulfides will be achieved by optimization of the topology in the Ti zeolite.
