3-Amino-10-aryl-2-arylimino-2,10-dihydrophenazines 1 undergo iodination in the 4-position of the phenazine nucleus yielding compounds which are identical with those obtained by oxidation of appropriate N-aryl-o-phenylenediamines with sodium iodate in the presence of acid. Bromination also takes place in this position but a second bromine atom enters the para-position of the arylimino moiety. The isomeric
3-氨基-10-芳基-2-芳基-2,10-二氢吩嗪1在吩嗪核的4位发生碘化反应,生成的化合物与通过用钠氧化适当的N-芳基-邻-苯二胺所获得的化合物相同酸存在下的碘酸盐。溴化也发生在该位置,但是第二个溴原子进入芳基氨基部分的对位。异构体10-芳基-3-芳基-氨基-2,10-二氢-2-亚氨基吩嗪2生成不稳定的碘代衍生物,但在吩嗪核的1位和4位以及邻位和对位溴化芳基氨基取代基的-位。初步的氯化实验表明,取代模式与为溴化产物建立的类似。还记录了通过与伯胺或仲胺反应从吩嗪环中除去溴和碘,并记录了它们被氢而不是胺残基取代的情况。
