title: Transition-metal-free synthesis of benzimidazoles mediated by KOH/DMSO.
abstract: Benzimidazoles are prepared by intramolecular N-arylations of amidines mediated by potassium hydroxide in DMSO at 120 °C. In this manner, diversely substituted products have been obtained in moderate to very good yields.
