The development of efficient and sustainable methodologies for the synthesis of N -heterocycles is a constant focus of organic synthesis. Herein we report an electrochemical method for the synthesis of benzimidazoles through dehydrogenative cyclization of easily available N-aryl amidines. The reactions are conducted under simple constant current conditions in a undivided cell without need for catalysts, chemical oxidants, or additives and produces H 2 as the only theoretical byproduct.
