Abstract

Kinetics of oxidation of diphenacyl sulphide (DPS) by imidazoliumdichromate (IDC) and quinolinium chlorochromate (QCC) hasbeen studied in 60% acetic acid under varying conditions. In boththe cases of study the order of the reaction is found to be one eachwith respect to oxidant and substrate. The rate in each case increaseswith the increase in acetic acid composition of the solvent and withincrease of [H+]. The reaction does not induce polymerisation ofacrylonitrile and addition of Mn(II) decreases the rate considerably.On the basis of the results, a suitable mechanism has been proposedfor each oxidation.
