In aprotic solvents, the reaction of hydroxide ion with electron accepters - iodine, tetracyanoquinodimethane, Nitro Blue Tetrazolium, methylviologen, 2,3,5-triphenyltetrazolium chloride, duroquinone, anthraquinone, benzil, 9-fluorenone, perylene - gave reaction products identical to those obtained by the reduction of these electron acceptors with electron donors. The paths of reaction of these electron accepters with hydroxide ion were found to be composed of successive one-electron reactions. The efficiency of the reaction showed a good correlation with the reduction potential of the electron acceptors; the rate of the reaction decreased with increasing the reduction potential of the electron acceptors.
