Benzimidazole derivatives have been synthesized using a catalytic amount of Fe(ClO4)3/SiO2 at room temperature with excellent yields
under solvent-free conditions. The solid phase conditions and use of a heterogeneous, and inexpensive catalyst are attractive features of this
method.
Key words: benzimidazole, Fe(ClO4)3/SiO2, heterogeneous, synthesis, catalyst
