with zinc chloride. In addition to the (I), these reactions afford comparable amounts of 2,21-diacetyl biphenyl (XIII). It has been possible to establish the identity of (I) from the carbonyl and enolic derivatives and products obtained in reactions of hydrolysis, oxidation, and reduction.
二苯并[a,c][1,3]环庚二烯-5,7-二酮(I)合成完成,合成了二苯并[a,c][1,3]环庚二烯(II)系列新成员通过(1)二苯甲酸二乙酯和乙酸乙酯在碱性催化剂下缩合,(2)二苯甲酰氯和钠丙二酸酯反应,以及(3)二苯酐和丙二酸酯与氯化锌缩合。除了 (I) 之外,这些反应还提供了相当数量的 2,21-二乙酰联苯 (XIII)。可以从羰基和烯醇衍生物以及水解、氧化和还原反应中获得的产物确定 (I) 的身份。
