Synthesis, characerization and electrochemical reduction of ferrocenylthioester

A new ferrocenylthioester was designed and synthesized by using ferrocene and 4-Iodobenzyl alcohol as starting materials.Ferrocenylthioester was reduced by electrochemical method.The experiments results indicated that electrochemical reduction was an effective method to prepare ferrocenylthiol from ferrocenylthioester,and SAM of ferrocenylthiol on Au electrode could be obtained.The current of the self-assembled modified electrode had a linear scaling with the scan rate in the blank solution.And Γ0 = 3.77 × 10-10 mol·cm-2,typical monomolecular layer,was obtained.
