An efficient method for the synthesis of imidazole derivatives by a three-component condensation of benzil or 9,10-phenanthrenequinone, aldehydes and ammonium acetate using supported ionic liquid-like phase (SILLP) catalyst under ultrasonic irradiation or classical heating conditions is reported. The present methodology offers several advantages, such as excellent yields, simple procedures, short reaction times, simple work-up and mild conditions. The catalyst is easily separated from the products by filtration and also exhibits remarkable reusable activity. These highly substituted imidazoles were also evaluated for their anti-microbial activity.
