The development of simple, efficient and general synthetic method for biological active compounds is one of the major challenges in organic synthesis. A simple and environmentally-friendly synthetic method for benzimidazoles, which are important structural motifs in many applications owing to their various biological functions, has been developed. Diamine and various substituted aldehydes are placed under UV lamp in the presence catalytic amount of zinc sulphate under solvent free condition.
