Reactions of 3-substitutedindoles, 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.
