Abstract

2-Aminobenzoimidazoles react with acetylene in the KOBut/DMSO superbase system (80°С, 20 min) to give benzoimidazo[1,2-a]imidazoles and benzoimidazo[1,2-a]pyrimidines, the products of self-organization of starting compounds with two or three molecules of acetylene. Moreover, vinyl derivatives of 1,3-dihydro-2H-benzo[d]imidazole-2-imine were obtained.
