2, 3-Diferrocenylbenzo [b] thiophene and 1, 3-diferrocenylbenzo [c] thiophene have been systematically and selectively synthesized from benzo [b] thiophene and phthaloyl dichloride, respectively. Characterization of the molecules was performed by physical and spectroscopic means and X-ray crystallographic analyses. The cyclic voltammograms of the novel thiophene derivatives containing ferrocene fragments showed a well-defined ...
