, p. 2370 - 2377 (2020/12/31)
A new approach to the synthesis of 3-nitroindoles using palladium-catalyzed arylation of nitromethane with N-(2-bromoaryl)imidates was developed. A convenient and rapid method for cyclization of ethyl N-(2-nitromethylaryl)acetimidates to 2-methyl-3-nitro-1H-indoles was proposed.

, p. 3282 - 3290 (2008/09/17)
The reaction of 2-phenyl- and 1-methyl-2-phenylindole with nitrogen dioxide or with nitrous acid (NaNO2-CH3COOH) in benzene leads mainly to the formation of the isonitroso and 3-nitroso indole derivatives, respectively. When reacted
ELECTRON-TRANSFER REACTIONS: REACTIONS OF INDOLES WITH NITROSONIUM ION. APPLICATION OF THE MARCUS THEORY. CRYSTAL STRUCTURES OF 1-METHYL-3,4-, 3,5- AND 3,6-DINITRO-2-PHENYLINDOLES

, p. 45 - 52 (2007/10/02)
A series of 1-methyl-2-phenyl-3-substituted indoles, when reacted with nitrosonium tetrafluoroborate, formed mainly 3-nitro, 3,4-dinitro and 3,6-dinitro derivatives.Although Marcus theory agrees with the feasibility of an electron transfer (ET) between th
Electrophilic ipso-Substitutions. Part 3. Reactions of 3-Substituted Indoles, 4-Substituted N,N-Dimethylanilines, and 1- and 3-Substituted Indolizines with Nitrous Acid
Colonna, Martino,Greci, Lucedio,Poloni, Marino
, p. 165 - 170 (2007/10/02)
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
Electrophilic ipso-Substitutions. Part 1. Reaction of 3-Substituted Indoles with Nitronium and Nitrosonium Ions
Colonna, Martino,Greci, Lucedio,Poloni, Marino
, p. 628 - 632 (2007/10/02)
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.
