Determination and Evaluation of the Second-Order Rate Constants for the Oxidation of Maleic and Fumaric Acid Derivatives with Alkaline Potassium Permanganate

Abstract

The second-order rate constants for the oxidation of maleic (Z-butenedioc) and fumaric (E-butenedioc) acid derivatives by potassium permanganate at pH 13 were determined. These constants varied by a factor of 10⁴. The results suggested that the rates of attack of the permanganate ion on the double bonds were largely governed by steric factors with electrostatic and electronic effects playing only a minor role.
