Synthesis, Structure, Electrochemistry, and Cytotoxic Properties of Ferrocenyl Ester Derivatives

Table 1

Redox potential of ferrocenyl esters in CH₃CN 1M CH₃CN 1M [NBuⁿ₄]PF₆ at a scan rate of 100 mV/s, referenced to ferrocene/ferrocenium redox couple. Ferrocene concentration of 2×10⁻³ M. E_1/2 is an average of the anodic and cathodic peaks potentials.
