A reversible cyclic voltammogram for the one-electron reduction of ferrocene in 1,2-dimethoxyethane is recorded under experimental conditions that enable the ferrocene anion to exist for a few minutes. The formal rate constant of the ferrocene0/− electrode, determined by cyclic voltammetry at −45°C, ca. 10−3 cm s−1, is in striking contrast with that of ferrocene+/0, > 10−1 cm s−1. The distortion of the ferrocene molecule caused by reduction may be a reason for this difference in electron-transfer rate.
