UV-vis spectra showing the reversible oxidation of (Bu4N)6 (0.19 mM) in CH3CN at −30 °C. (solid black) (Bu4N)6; (solid red) after addition of 1 equiv. Fc+PF6−; (dashed black) subsequent addition of 1 equiv. Cp*2Fe; (dashed red) addition of second 1 equiv. Fc+PF6−. Note: the feature at ~790 nm corresponds to ferrocene.
