Abstract
Polarographic studies have been carried out in acetone on the dithio(acetylacetonato)‐complexes and . The iron and osmium complexes are reversibly reduced at the DME, whereas the ruthenium complex undergoes a quasi‐reversible reduction. For the d5 systems the electrode reaction is believed to be . However reduction of is highly irreversible and may involve adsorption or compound formation at the mercury surface. Millieoulometric studies indicate the electrode reaction is . The half‐wave potentials accord with the known chemistry and spectroscopic properties of the complexes. The development of polarographic techniques for use in acetone is described in detail.Keywords
