Synthesis of Ferrocene Derivatives Allowing Linear Free Energy Studies of Redox Potentials

Abstract

AbstractA series of ferrocene derivatives, which have diverse redox potentials modulated by functional groups, have been synthesized as potential ‘multi‐potential’ probes. A Hammett constant analysis revealed a linear free energy correlation between the redox potentials and the electron density of the ferrocene derivatives as determined by the choice of functional group used to modify the ferrocene core.
