Z. Stec et al., OXIDATION OF SULFIDES WITH H2O2 CATALYZED BY NA2WO4 UNDER PHASE-TRANSFER CONDITIONS, Polish Journal of Chemistry, 70(9), 1996, pp. 1121-1123
A simple and efficient method was developed for the synthesis of selec
ted dialkyl, alkylaryl and diaryl sulfones via oxidizing respective su
lfides with hydrogen peroxide in the two-phase, water-dichloroethane s
ystem in the presence of Na2WO4 and [Bu(4)N]Cl.
