Abstract:

Ferrocene derivatives have been synthesized by the Suzuki cross-coupling reaction of ferroceneboronic acid with various aryl/heteroaryl halides. The reactions yield ferrocenyl derivatives with overall yields varying between 35 and 98%. The derivatives have been characterized by ¹H NMR, ¹³C NMR, IR, HRMS and elemental analysis. The structure–property relationship has been investigated based on UV/Vis spectroscopy and cyclic voltammetry. Cyclic voltammetry studies revealed when the side group of ferrocenes were an electron-donating, lower oxidation was displayed. On the other hand, the strong electron-withdrawing group had a higher oxidation potential.
