Chloroacetylferrocene reacted with sodium sulfide to give bis(ferrocenoylmethyl) sulfide in moderate yield. The reaction of bis(ferrocenoylmethyl)sulfide with the Lawesson reagent gave 2,6-diferrocenyldithiin in high yield, which was led to 2,5-diferrocenyl thiophene by the oxidation with hydrogen peroxide. Bis(ferrocenoylmethyl)sulfide reacted with TiCl4/Zn in refluxing THF and subsequently dehydrogenated by Pd/C to give 3,4-diferrocenylthiophene in moderate yield. The cyclic voltammetry of the thiophene derivatives showed that the 2,5-isomer had larger electron-delocalization in the one electron-oxidized species(the mixed-valence complex) than the 3,4-isomer.
