Kinetics and mechanism of Ru(III) catalyzed oxidation of butyl digol by N-bromosuccinimide

Kinetics and mechanism of Ru(III) catalyzed oxidation of butyl digol by N-bromosuccinimide (NBS) has been extensively studied at 35degreesC under Ostwald isolation condition. Kinetic findings indicate first order reaction kinetics in oxidants, substrates, H+ ions and catalysts, respectively. There is no significant influence of successive addition of mercuric acetate, succinimide and sodium chlorate on redox reaction rate. On the other hand, it shows decreasing effect on addition of potassium chloride on reaction rate. On the basis of the experimental observed kinetic findings, the proposed rate expression is -d[NBS]/dt=K[NBS][H+][S][Ru(III)]/K-1[H2O]+[Cl-].
