摘要：

In a one-pot four-component reaction, an aldehyde, an amine, benzil and ammonium acetate were condensed for the synthesis of 1,2,4,5-tetrasubstituted imidazoles in the presence of silica supported antimony pentachloride (SbCl5.SiO2) in improved yields. The catalyst is recoverable by simple filtration and can be used in the subsequent reactions.
