Аннотация: A new superbase-promoted reaction of acetylene involves self-organization of its three molecules with one molecule of arylamine in KOH/DMSO system to afford 1-aryl-2,5- dimethylpyrroles in up to 63% yields. The key step of this reaction cascade is assumed to be the nucleophilic addition of acetylene to the C=N bond of the intermediate aldimine (aza-Favorsky reaction).

Ключевые слова: acetylene, arylamines, imines, pyrroles, superbases, vinylation, ethynylation..
