3-Substituted indoles react with nitronium and nitrosonium ions to yield 3-nitroindole.In both cases the reaction was interpreted as an electrophilic ipso-substitution.The reaction mechanism is interpreted by hypothesizing the formation of a ?-complex-like intermediate, wich is some cases is preceded by an electron-transfer process.An order for the leaving abilities of the different electrofugal groups is discussed.
