Kinetic study of oxidation of some thioacids bybis(2,2′-bipyridyl) copper(II) permanganate
Oxidation of thioglycollic, thiolactic and thiomalic acids, to the corresponding disulphide dimers, bybis(2,2′-bipyridyl) copper(II) permanganate (BBCP) is first order with respect to BBCP and exhibits Michaelis-Menten type kinetics with respect to the thioacid. The reaction is catalysed by hydrogen ions. The rate decreases with an increase in the amount of acetic acid in the solvent. There is no effect of added bipyridine and acrylonitrile. A mechanism involving formation of a sulphenium cation in the rate-determining step has been proposed.
