Kinetic study on rhodium(III) catalyzed oxidation of 3-ketoglutaric acid by acid medium of bromamine–T in the presence of þ- toluenesulphonamide has been carried out. The reaction follows first order with respect to 3- ketoglutaric acid. The first order kinetic was found with respect to Rh(III) chloride. Hydrogen ion shows positive effect on reaction rate. A negative effect of [Cl¯] and insignificant effect of ionic strength of the medium were observed on the reaction velocity. A plausible mechanism of the reaction has also been proposed
