pounds, presumably oligomers. In glacial acetic acid (CH3C0,H/CH2C12=3 :2, i=40 mA/cm2, T=2OoC, Pt electrode) 17% androstanyl acetate is obtained and 38% androstane is recovered. Remarkable is the selectivity of the oxidation: We found that the 6-(6a), 7-, and 12-acetates are formed in the ratio 35
