Tetrabutylammonium Chlorite as an Efficient Oxidant for Controlled Oxidation of Sulfides to Sulfoxides.

Considering the demand for organosulfur materials and the challenges associated with currently used oxidation processes, in this study, we evaluated the counter-cation of sodium chlorite (Na+ClO2-) with tetrabutylammonium chloride (Bu4N+Cl-) to synthesise tetrabutylammonium chlorite (Bu4N+ClO2-). Bu4N+ClO2- exhibited good solubility in organic solvents like chloroform (1.6 g mL-1) and ethyl acetate (0.
