    • Abstract


      The oxidation of 4,4′-disubstituted diphenyl sulphoxides by potassium permanganate on Hammett type correlations give a small positive ρ value (0.34). This is in contrast to the oxidation of aryl methyl sulphides (ρ = −1.36) by the permanganate ion. On the basis of rate data a mechanism of nucleophilic attack of MnO4 on the substrate has been proposed.
