Kinetics and Mechanism of Oxidation of Some Cycloalcohols by Acidic Solution of Bromamine-T

Abstract

Kinetic investigations on Ru(III) catalysed oxidation of methyl cyclohexanol (M-cyhol) and 4-methyl cyclohexanol (4-M-cyhol) by acidic solution of bromamine-T (BAT) have been made in the temperature range 25º–40ºC. The reaction shows first order kinetics in BAT, both cyclic alcohols, H⁺ ions and Ru(III). Insignificant effect of addition of p-toluenesulphonamide (PTS), as one of the reaction products, was observed. The reaction rate decreased on increasing Cl^– while practically no effect of variation of ionic strength of the medium was observed. A suitable mechanism in agreement with observed kinetic data has been proposed.
