Reactions of 3-substituted indoles, N,N-dimethylanilines, and 1- and 3-substituted indolizines with nitrous acid yield products of ipso-substitutions, essentially the corresponding nitro-derivatives. An electron transfer process is proposed for the initial step, on the basis of reaction products, e.s.r. evidence, and substrate oxidation potentials.
3-取代的吲哚,N,N-二甲基苯胺以及1-和3-取代的吲哚嗪与亚硝酸的反应产生ipso-取代的产物,基本上是相应的硝基衍生物。根据反应产物,esr证据和底物氧化电位,提出了第一步电子转移过程。
