4-position and the corresponding N-alkyl-1,3-cyclohexadien-1-amines undergo regioselective iodination and aromatization to give 2-iodophenols and N-alkyl-2-iodoanilines, respectively, upon reaction with iodine and sodium alkoxide. By contrast, N,N-dialkyl-1,3-cyclohexadien-1-amine derivatives undergo non-iodinative aromatization to simple N,N-dialkylanilines under similar conditions.
在4-位含有吸电子基团的2-环己烯酮和相应的N-烷基-1,3-环己二-1-胺进行区域选择性碘化和芳构化,分别得到2-碘酚和N-烷基-2-碘苯胺。与碘和醇钠反应后。相反,N,N-二烷基-1,3-环己二-1-胺衍生物在类似条件下经历非碘代芳构化为简单的N,N-二烷基苯胺。
