Oxidation of (+)-(R)-Pantothenic Acid by Aqueous Alkaline Potassium Permanganate: A Kinetic and Mechanistic Approach

Abstract

The kinetics of oxidation of (+)-(R)-pantothenic acid (PA) by permanganate in aqueous alkaline medium at constant ionic strength 0.20 mol dm

Kinetics and Mechanism of Oxidative Decarboxylation of Benzilic Acid by Alkaline Permanganate Using the Stopped-Flow Technique

“…It is also known that, permanganate ion in alkaline medium 22 exists as MnO 4 .OH 2-. As the pK a of benzilic acid is less than 4, it will be present largely as the carboxylate anion 23 in the present experimental conditions. Based on the experimental results, a mechanism can be proposed for which all the observed orders with respect to each constituent such as oxidant, reductant and OHmay be well accommodated.…”
