A Simple and Selective Oxidation of Sulfides to Sulfoxides Using Tetrabutylammonium Peroxydisulfate: A Rebuttal

Abstract

The report that oxidation of sulfides to sulfoxides using tetrabutylammonium peroxydisulfate (2) in methylene chloride was found to be erroneous. We repeated the procedure described in the paper and found that oxidation of sulfide to sulfoxide could not be achieved with the method.
