Rate-determining electron-transfer reactions in highly aqueous alcohol–water mixtures. A quantitative analysis of solvent effects on the oxidation of 4-methoxyphenylacetate by potassium 12-tungstocobaltate(III)

Abstract

Kinetic solvent effects on the rate-determining outer-sphere electron-transfer reaction between 4-methoxy-phenylacetate and potassium 12-tungstocobaltate(III) in highly aqueous alcohol–water mixtures are quantitatively analysed in terms of pairwise Gibbs energy parameters for interaction of the initial and transition state with the cosolvent.
