other mercury salts on the reaction were also studied. Treibs oxidation was successful in chloroform, carbon tetrachloride, and dibromomethane, but not in other solvents tested. 3β-Acetoxy-6-bromomercuriandrost-5-en-17-one was obtained in dibromomethane. Replacement of the reagent by mercury(II) trichloroacetate altered the intermediates formed but not the products. Mercury(II) tribromoacetate was unreactive
摘要 研究了C-3 取代基对雄性5-烯与三氟乙酸汞(II) 在二氯甲烷中反应(改性Treibs 氧化)的影响。3β-Acyloxyandrost-5-en-17-ones 得到 3β-acyloxy-6β-hydroxyandrost-4-en-17-ones 伴随着 3β-acyloxy-6-chloromercuriandrost-5-en-17-ones。3β-Acetoxy-6β-trifluoroacetoxyandrost-4-en-17-one 和 3β-acetoxy-4β-trifluoroacetoxyandrost-5-en-17-one 是反应的中间体。氯汞类固醇的形成表明溶剂参与了反应。以 3α-acetoxyandrost-5-en-17-one 作为底物,观察到产物分布的完全逆转。3β-Haloandrost-5-en-17-ones 的主要产物反映了卤化物的
