Polarographic reduction of androsten-3-ones, androsten-7-ones, and pregnen-20-ones was carried out in aqueous dimethylformamide solution and the relationship between the half-wave potential and the nature of the conjugated ketone system, i.e., the position of the carbonyl group and the number of the double bond, was examined (Tables I, III, and IV). In each series, the more the conjugated double bond was elongated, the easier was the reduction of unsaturated ketone. The result of controled-potential electrolysis with some unsaturated ketosteroids revealed the electron-number that participated in the polarographic reduction (Table II).
