carboxylic acid to the lactone (II; R = H) has been accomplished by oxidation with chromic acid or hydrogen peroxide and its derivatives, by decomposition of the diacyl peroxide derived from this acid, and by electrolysis of its sodium salts. From the effects of several 3′-substituents (R = OMe, NHCOCH3, CH, NO2) on these reactions it has been concluded that the oxidations with chromic acid and hydrogen
通过用铬酸或过氧化氢及其衍生物氧化,分解由该酸衍生的二酰基过氧化物并对其钠进行电解,可以完成二苯基-2羧酸脱氢成内酯(II; R = H)的反应。盐。从几种3'取代基(R = OMe,NHCOCH 3,CH,NO 2)对这些反应的影响,可以得出结论,铬酸和过氧化氢等的氧化是通过氧化剂与羧酸的连接而进行的。基团和相邻环中随后的阳离子类化合物取代。自由基(III)被认为是另外两个环化中的中间体。
