Аннотация: Intramolecular carboazidation of N-arylacrylamides with 1-azido-1λ³-benzo[d][1,2]iodaoxol-3(1H)-one (the N₃-Togni reagent) affording 3-(azidomethyl)indolin-2-ones proceeds at room temperature under visible light irradiation with 2,4,5,6-tetra(carbazol-9-yl)-1,3-dicyanobenzene assistance. The latter provides the formation of azido radicals from the N₃-Togni reagent. The investigated substrate scope involves 12 examples.

Ключевые слова: carboazidation, arylacrylamides, indolin-2-ones, radical cyclization, N₃-Togni reagent, photocatalysis.
