摘要：

A simple and efficient one pot synthesis of 1,2,4,5-tetra substituted imidazoles is achieved by condensation-cyclization reaction of benzil, aromatic aldehyde, 2-amino ethyl pyrrolidine, ammonium acetate using fly ash loaded Bi2O3-ZnO. Different substituted aldehydes have been used in this reaction. The process is operationally simple, environmentally safe and has magnificent yield. Furthermore this catalyst can be recycled at least four times without any loss of activity.
