The terminal product in the Friedel and Crafts methylation of benzene and its methyl homologues is 1,1,2,3,4,5,6-heptamethylbenzenonium ion (I), a new comparatively stable carbonium ion. The ion decomposes slowly in aqueous acid to methanol and hexamethylbenzene (III) and can be synthesized from these products by treatment with sulfuric acid. (I) is in rapidly reversible equilibrium with a proton and
苯的Friedel and Crafts甲基化及其甲基同系物的最终产物是1,1,2,3,4,5,6-庚七甲基苯氮鎓离子(I),这是一种新的相对稳定的碳鎓离子。离子在酸水溶液中缓慢分解为甲醇和六甲基苯(III),可以通过用硫酸处理从这些产物中合成。(I)与质子和中性分子C 13 H 20处于快速可逆的平衡,其结构4-亚甲基-1,1,2,3,5,6-六甲基环己二烯-2,5(II)已分配。
