Oxidation of DL - Methionine by Imidazolium Chlorochromate and Benzimidazolium Chlorochromate in Aqueous Perchlorate Medium

Abstract

Abstract:The oxidation of methionine by oxidants such as imidazolium chlorochromate (ICC) and benzimidazolium chlorochromate (BCC) in aqueous perchlorate medium has been studied spectrophotometrically over the range 3.00 ≤ ) for the electron transfer reaction were found to be 12.5 and -154.1 in case of in case of BCC respectively. The product of the reaction was found to be methionine sulphoxide. The negative values of ΔS ≠ support ordered transition state for both the electron transfer reactions due to ICC and BCC.
