The redox potentials of [Fe(CpSMe2)2]2+ (CpSMe2= dimethysulfoniumcyclopentadienflide), [Ni(CpSMe2)2]2+, [Co(CpSMe2)2]2+, [Mn(CpSMe2)2]2+, (CpPPh3)HgBr2 (CpPPh3= triphenylphosphoniumcyclopentadienylide), (CpPPh3)HgCl2, and MoPC (PC = phthalocyanine) were examined using cyclic voltammetry (CV). The experimentation was carried out in a temperature controlled environment. With the exception of the mercury and molybdenum complexes, the solvent system consisted of 15 milliliter mixture of acetonitrile and water. Due to the solubility problems of the mercury bromide complex, dimethylformamide (DMF) was used as the solvent. Pure acetonitirile was used for the mercury chloride and molybdenum complexes.
The emphasis of this research was directed towards the iron complex. Its complimentary pure metallocene FeCp2(Cp = cyclopentadiene) is well characterized, thereby permitting a comparison of the two complexes. The iron sulfonium ylide complex was found to have lower redox potentials. This supports the anticipated effect of the added dimethylsulfonium (SMe2) group.
