Solid Silica-based Sulphonic Acid as an Efficient Green Catalyst for the Selective Oxidation of Sulphides to Sulphoxides using NaCIO in Aqueous Media
Abstract
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.
