Popis: Introduction: In this present investigation, efficient and general protocols for the synthesis of a series of imidazoles 4(a-p) derivatives have been developed by cyclocondensation of aromatic aldehydes, benzil and ammonium acetate in the existence of efficient [EMIm][BH3CN] ionic liquid catalyst under microwave condition in good to excellent yields (91 97%). Method: The structures of the synthesized compounds have been confirmed by IR and NMR spectra. Result: The significant features of this protocol are an uncomplicated workup process, rate enhancement with high yields, and efficient catalysts. Conclusion: It was concluded that [EMIm][BH3CN] is the finest catalyst under MW heating conditions.
