Kinetics of the reduction of some perbenzoic acids by iodide ions

Abstract

The kinetics of the reduction of some ring-substituted perbenzoic acids by iodide ions have been investigated in different protic solvents and in water–dioxan mixtures. The rates are independent of the ionic strength and of the hydrogen-ion concentration, and the reaction is of the first order in peroxide concentration and in iodide-ion concentration. The results are discussed in terms of the participation of protic solvents in the activated complex.
