Abstract Reaction Between Novel Compound; N, N′ dibromo-N, N′ -1,2- ethylene bis(2,5- dimethyl benzene sulfonamide) and aromatic compounds in the carbontetrachloride produces bromo aromatic compounds. In the case of benzene rings that contain mono activated substituted, only para - bromo isomer was formed. At the presence of benzoyl peroxide in the reaction mixture α - Hydrogen from alkyl side chain
新化合物之间的抽象反应;N,N'二溴-N,N'-1,2-亚乙基双(2,5-二甲基苯磺酰胺)与芳族化合物在四氯化碳中生成溴代芳族化合物。在含有单活化取代的苯环的情况下,仅形成对溴异构体。在反应混合物中存在过氧化苯甲酰的情况下,来自烷基侧链的α-氢被溴取代。
