Abstract: The kinetics of oxidation of several esters of 3-oxobutanoic acid by Ce(IV) ions in a solution of sulfuric acid was studied. The values of the rate constant k₂, corresponding to the rate equation v = k₂ [Ce(IV)] [ester], correlate with the values of substituent constants  σ* in the sense of Taft equation. On the basis of our kinetic measurements of the Belousov—Zhabotinskii reaction with esters of 3-oxobutanoic acid, we can conclude that some its parameters (the averaged frequency of oscillations and the averaged period of oscillations) also correlate with the values of substituent constants σ* in the sense of Taft equation.
