The rates of homogeneous electron-transfer reactions between radical anions and neutral molecules were studied in a variety of tetracyanoethylenide systems in order to obtain information concerning the counterion effect on the electron-transfer reactions. The estimated values of the rate constants had the same order of magnitude at room temperature for all the systems, while the activation energies and the preexponential factors were markedly dependent on the natures of the counterions and the solvents. The obtained results are discussed in terms of the forms and structures of the radical anions.
