Efficient Synthesis of Benzimidazole and Quinoxaline Derivatives with ZnO.H2O2 under Mild Conditions

G. A. Meshram and Vishvanath D. Patil

Various benzimidazoles and quinoxalines derivatives have been synthesized with excellent yields using a catalytic amount of zinc oxide with hydrogen peroxide (ZnO.H2O2) at room temperature. The advantages of this synthetic protocol are a wide substrate range, easy handling and commercially available inexpensive catalyst.
