| مستخلص: |
2-Aminobenzimidazoles react with acetylene in the KOBut/DMSO superbase system (80°C, 20 min) to give benzimidazo[1,2-a]imidazoles and benzimidazo[1,2-a]pyrimidines formed by the self-assembly of the starting compounds with two or three molecules of acetylene. Vinyl derivatives of 1,3-dihydro-2H-benz[d]imidazole-2-imine were also isolated. [ABSTRACT FROM AUTHOR] |
