| Abstract: | Oxidation of alkyl aryl sulphides by N-bromosuccinimide (NBS) in the presence of mercuric acetate exhibits a clean second order kinetics, first order in each reactant. Change in ionic strength, added suecinimide and mercuric acetate have no effect on the rate. The reaction affords a negative ρ-value (-2.0). Addition of H+ catalyses the reaction. These results point to a mechanism involving the rate-limiting electrophilic attack of NBS in neutral medium (and of NBS as well as NBSH+ in acid medium) on the sulphide sulphur resulting in the formation of sulphonium ion which undergoes fast hydrolysis to sulphoxide. |
