Kinetics and mechanism of ruthenium(III) catalyzed oxidation of secondary alcohols by bromamine-T in hydrochloric acid solutions
The kinetics of oxidation of 2-propanol, 2-butanol, 2-pentanol, 2-hexanol, and 2-heptanol by sodium N-bromo-p-tolue-nesulfonamide (bromamine-T or BAT) to the corresponding ketones in the presence of HCl and catalyzed by ruthenium(III) chloride has been studied at 30C. The reaction rate shows a first-order dependence on [BAT] and a fractional-order each on [alcohol], [Ru(III)] and [H+]. Addition of the reaction product, p-toluenesulfonamide, retards the rate. An increase in the dielectric constant of the medium decreases the rate. Variations of ionic strength and halide ion concentration have no effect on the rate. Rate studies in D2O medium show that the solvent isotope effect, k?(H2O)/k?(D2O), equals 0.67. Proton inventory studies were carried out using H2O-D2O mixtures. Attempts have been made to arrive at a linear free-energy relationship through the Taft treatment and observed that the rate constants do not correlate satisfactorily. An isokinetic relationship is observed with beta= 354K indicating that enthalpy factors control the rate which is also confirmed by the Exner criterion. A mechanism consistent with the observed kinetics has been proposed and discussed.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: Cl3Ru, you can also check out more blogs about10049-08-8
