Kinetics of symmetric electron exchange reaction in series of substituted nitrobenzenes: Influence of reactant structure

Kinetic data on symmetric electron exchange in substituted nitrobenzenes have been obtained by means of ESR. The logarithm of the electron exchange rate constant varies linearly with the square of the constant of hyperfine splitting on the nitrogen atom of the nitro group. On the basis of the results obtained, it is concluded tentatively that solvation of the nitro group plays a decisive role in the kinetics of symmetric electron exchange in this series of compounds.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 25, No. 6, pp. 688–693, November–December, 1989.
