The title reaction effected in oleum at 150 °C gives a quantitative yield based on chlorine of a mixture of 1,3,5-trichloro-2,4,6-trinitrobenzene and 1,2,3,5-tetrachloro-4,6-dinitrobenzene; the dependence of product ratios on acidity, effects of additives, and results of isotopic-labelling studies indicates that the latter product is formed via reversible ipso-attack of nitronium ion at a nitro-substitute
在150°C的发烟硫酸中进行的标题反应可得出基于氯的1,3,5-三氯-2,4,6-三硝基苯和1,2,3,5-四氯-4,6混合物的定量收率-二硝基苯;产物比例对酸度的依赖性,添加剂的作用以及同位素标记研究的结果表明,后者的产物是通过硝基取代位置上的硝基离子可逆的ipso攻击形成,然后进行亲核捕获而生成的二烯,可能是氧化后的亲电子形式的氯,用于与原料反应。
