Peroxy Acid Oxidations: A Kinetic and Mechanistic Study of Oxidative Decarboxylation of $\alpha$-Keto Acids by Peroxomonophosphoric Acid

  • Published : 20010800


The kinetics of oxidative decarboxylation of pyruvic acid and benzoylformic acid by peroxomonophosphoric acid (PMPA) in aqueous medium have been investigated. The reaction follows second order-first order each in PMPA and substrate concentration a t constant pH. The reactivity of different peroxo species in the oxidation has been determined. Activation energy and thermodynamic parameters have been computed. A plausible mechanism consistent with the observed results is proposed.
