Visible-light promotes an atomic substitution reaction of thiocacids to afford various alkyl and aryl carboxylic acids in over 90% yields with dimethyl sulfoxide (DMSO) as the oxygen source. The atomic substitution process proceeds smoothly through the photochemical reactivity of the formed hydrogen-bonding adduct between thioacids and DMSO.
