| Abstract: | The kinetics of oxidation of dimethyl sulfoxide by periodate, has been carried out in the presence of palladium(II) catalyst in alkaline medium at 298 K. The stoichiometry is [DMSO]: [IO4-] = 1:1. The reaction exhibits first order dependence with respect to [IO4-], an apparent less than unit order in [DMSO], [OH-] and [palladium(II)] under the experimental conditions. A probable mechanism is proposed. The reaction constants involved in the different steps of the mechanism have been calculated. The activation parameters with respect to slow step of the mechanism have been computed and discussed. |
