- Abstract
The metal-free oxidation of sulfides to sulfones using sodium bromate (NaBrO3) in [bmim]HSO4:H2O (3:1, v/v) at 80 °C is reported. Phenylalkyl, phenylbenzyl, diaryl and heteroaryl sulfides were transformed to the corresponding sulfones. Aryl tellurides and phosphines were oxidised to the corresponding telluroxides and phosphine oxides. All the reactions proceeded smoothly and gave high yields in 20-55 min. The ionic liquid [bmim]HSO4 was easily recovered and recycled.
