Abstract
Kinetics of oxidation of cyclopentanone (Cyp) and cyclohexanone (Cyh) by bromamine-B (BAB) in perchloric acid medium have been reported. The rate shows zero order dependence in BAB and first order dependence on both cyclic ketones and hydrogen ion concentration have been observed. Variation of ionic strength of the medium, addition of bromide ion and benzenesulphonamide which is one of the reaction products have no effect on the rate. The rate of the reaction increases with decrease in the dielectric constant of the medium. The proposed mechanism involves acid catalysed enolisation of cyclic ketones in the slow and rate determining step, followed by its fast interaction with BAB giving corresponding 1, 2—diketones as final products. Thermodynamic parameters have been computed by studying the reaction at different temperatures (303—318 K).
