Herein we describe a Cu-catalyzed radical addition and oxidation cascade reaction for the chemo/regioselective synthesis of unsymmetrical indole trimers (isotriazatruxenes, i-TATs) from easily available starting materials. The i-TATs exhibited blue fluorescence in various solvents with different fluorescence intensities and showed good structural expansibility. A wider range of products could be used in optoelectronic materials by developing suitable derivatives.

A new synthetic method for triazatruxenes from indoles is developed using N-bromosuccinimide (NBS) as a user-friendly reagent. Major reaction parameters including the amount of NBS, substrate concentration, temperature, addition rate and addition method are investigated. Additional experiments are also conducted in order to gain access toward the reaction mechanism. Compared to the use of Br2 in the conventional method, this reaction requires less reaction time, provides better yields, and displays excellent reproducibility. The reaction can be conveniently performed at 10 g scale and it is also applicable to several substituted indoles, benzoindole, and N-alkyl indoles.

The reactions of indole with nitrosobenzene in the presence of acetic, monochloroacetic, monobromoacetic and trichloroacetic acid afford as the main product a deep-green precipitate, which in a preceding study had been erroneously identified as the aminyl radical of a trimer indole. The identity of the minor products was confirmed. This paper deals with the determination of the correct structure of the compounds contained in the precipitate through a study based on chemical reactions, electrochemical measurements and X-ray analysis.
