experimental part, p. 1134 - 1141 (2010/04/29)
A green and efficient method for the synthesis of 2,4,5-triarylimidazoles by one-step condensation reaction of benzil, aromatic aldehyde, and ammonium acetate under catalyst-free, solvent-free, and microwave-irradiation conditions is reported. This method had many dramatic advantages, such as the short reaction time (3-5min), good yields (80-99%), environmental friendliness, and convenient operation.
