Investigation of Electron Transfer Mechanistic Pathways of Ferrocene Derivatives in Droplet at Carbon Electrode

The results of cyclic, differential pulse and square wave voltammetric studies four ferrocene derivatives, i.e., 4-ferrocenyl-3-methyl aniline (FMA), 3-Chloro-4-ferrocenyl (CFA), 4-ferrocenyl (FA) ferrocenyl benzoic acid (FBA) on carbon electrode, revealed that the redox behavior these compounds is sensitive to pH, concentration, scan number rate. One electron, diffusion controlled, with a quasi-reversible signal displaying ferrocene/ferrocenium couple was observed for each studied derivatives. Quasi-reversibility this evidenced by ?Ep, Ia/Ic current ratio ksh values. Another one electron proton irreversible oxidation noticed in voltammograms except FBA. This corresponds electro-oxidation amine group its irreversibility, as supported values, due influence donating nature group. A electrochemical parameters such D, ksh, LOD LOQ were evaluated targeted obtained are expected provide insights into mechanism understanding their biochemical actions. electrochemistry presented work done using unique environmentally benign cost-effective droplet approach.
