Ruthenium(III) Catalyzed Oxidation of Diphenyl Sulfoxide by N-Sodio-N-Bromobenzenesulfonamide in Hydrochloric Acid: a Kinetic Study
The kinetics of oxidation of diphenylsulfoxide (DPSO) by N-sodio-N-bromobenzenesulfonamide also known as bromamine-B (BAB) has been studied in HCl solution at 30¡ãC. In the absence of Ru(III), the rate shows a first-order dependence on [BAB] and fractional-order dependence each on [DPSO] and [H(+)]. In the presence of Ru(III), the rate is firstorder with respect to [BAB] and fractional-order each on [DPSO], [H(+)] and [Ru(III)] at low acid concentration. At high acid concentration the reactionrate shows a first-order dependence each on [oxidant], [DPSO] and [H(+) ] and fractional-order on [Ru(III)]. The variation of the ionic strength, dielectric constant of the medium and addition of chloride ion and thereaction product of BAB (benzenesulfonamide) do not have any significan t effect on the reaction rate. The activation parameters have been evaluated. The value of the protonation constant of monobromamine-B, 84.7 at 303 K, is evaluated from the proposed mechanism. Mechanisms consistent with the observed kinetic data have been proposed.
