The Relationship Between the Bridging Alkyl Group and Electrochemical Behavior of Some Biferrocenyl Alkanes

Abstract

Abstract: The cyclic voltammetric behavior of some alkyl-bridged biferrocene compounds are reported. It was found that the stable conformation is the decisive factor influencing their electrochemical properties. The larger the angle between the two ferrocenyl groups and the bridge carbon deviates from 109°28', the greater the Δ E_pvalue bocomes. Besides, the electrochemical behavior of some 6-acyl, 6,6'-diacyl alkyl bridged biferrocene derivatives are investigated and the factors affecting their electrochemical behavior are also discussed. Acyl group exerts an electron withdrawing effect on the ferrocenyl moieties, which makes them more difficult to be oxidized than their parent compound.

Key words: Biferrocenyl alkanes, Substituent effect, Cyclic voltammetry
