Seven novel ferrocene derivatives containing (methylamino)benzonitrile and N-methylnitroaniline groups (3a-3f and 4) have been synthesized by conventional methods and characterized by FT-IR, NMR and cyclic voltammetry. The electrochemical behavior of these compounds (3a-3f) has been studied by cyclic voltammetry measurements at a platinum electrode in acetonitrile/0.1 M TBAP. The ferrocenyl group in all compounds showed similar reversible one-electron redox process, suggesting that the ferrocene moieties are equivalent and that there are no interactions among them. The formal potential, , is shifted to the more positive potential, indicating that the (methylamino)benzonitrile and N-methylnitroaniline introduced to ferrocene moiety exercise an electron-withdrawing effect.
