Assembly of annulated 1,3-diazapyrenes by consecutive cross-coupling and cyclodehydrogenation of (het)arene moieties / E. V. Verbitskiy, E. M. Dinastiya, O. S. Eltsov [et al.] // Mendeleev communications. - 2020. - Vol. 30, № 2. - P142-144 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Di(het)areno[e,l][1,3]diazapyrene core was constructed by FeCl3-mediated intramolecular oxidative cyclodehydrogenation of 5-[2,6-di(het)arylphenyl]pyrimidine precursors, which in turn were obtained by the Suzuki cross-coupling of 5-(2,6-dibromophenyl)pyrimidine derivative with the corresponding (het)arylboronic acids. Molecular orbital calculations as well as redox and photophysical measurements show that the fused products are promising for organic electronic application. |
