Primary and tertiary nitronate ions and sulphonyl bromides and iodides rapidly equilibrate with the nitrohalides and sulphinate ion. Products are determined by solvent and by the occurrence of cross-equilibrium reactions, some of which have single-electron-transfer mechanisms. The reaction of arene-sulphinate and -thiolate ions with 1,2-dibromo-2-nitro-1-phenylethane gave E-β-nitrostyrene by Z-philic
伯硝酸盐和叔硝酸盐离子和磺酰溴和碘化物与硝基卤化物和亚磺酸盐离子快速平衡。产物取决于溶剂和交叉平衡反应的发生,其中一些反应具有单电子转移机理。在两种情况下,芳烃-硫酸盐和-硫醇盐离子与1,2-二溴-2-硝基-1-苯基乙烷的反应均通过Z-亲电消除得到E -β-硝基苯乙烯,但亲脂性也得到更碱性的硫醇盐离子消除,2-溴-2-硝基-1-苯基乙烯。
