oa South African Journal of Chemistry - Solid silica-based sulphonic acid as an efficient green catalyst for the selective oxidation of sulphides to sulphoxides using NaCIO in aqueous media : research article



A range of sulphides can be selectively oxidized to the corresponding sulphoxides in good yields using NaClO / silica sulphonic acid as an efficient and recyclable solid acid catalyst, in both water and 50 / 50 water / EtOH as solvents. The new method compares favourably with previous methods in the literature.
