Electrophilic ipso-Substitutions. Part 3. Reactions of 3-Substituted Indoles, 4-Substituted N,N-Dimethylanilines, and 1- and 3-Substituted Indolizines with Nitrous Acid
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
