The para orientation by the carbonyl groups in the bromination of phenanthrenequinone derivatives has been explained on the basis of an excited state resulting from thermal excitation of the quinone and/or from a n→π* transition of the nonbonding electrons of the oxygen atoms. A general preparative method for the syntheses of 3-bromophenanthrenequinone derivatives has been developed. The structure
已经基于由醌的热激发和/或由氧原子的非键电子的→π *跃迁产生的激发态解释了菲醌衍生物的溴化中羰基的对位取向。已经开发了合成3-溴苯并菲醌衍生物的通用制备方法。通过降解已经建立了2-硝基-6-溴代菲醌的结构。描述了2-硝基-6-溴芴酮的合成。还描述了菲醌直接溴化为2-溴和2,7-二溴衍生物。
