Bisbiphenylchromium(I) and ferrocene as reference redox systems for the comparison of half wave potentials in different solvents


Bisbiphenylchromium(I) and ferrocene are shown to represent suitable reference redox systems in a number of non-aqueous solvents. The difference of their half-wave potentials is nearly equal in each solvent, namely between 1.12 and 1.13 V. Specific interactions are involved between ferriceniumion and water. The extrapolated half-wave potential of bisbiphenylchromium(I) (−0.78±0.04 V vs. sat. Ag/AgCl-electrode) is not substantially influenced by water.
