摘要：

The formation of 2,4,5-triphenylimidazole by the condensation of benzil with benzaldehyde and ammonium acetate in glacial acetic acid at 110° has been kinetically studied by means of uv and visible spectrophotometry. The rate equation is v = k [benzil] [AcONH4]2, where k varies slightly with varying initial concentration of benzaldehyde and the extent of variation of k depends on the substituent of benzaldehyde. The effect of substituents of benzil is small. These results suggest a mechanism involving the formation of benzil diimine (III) and the addition of III to benzaldehyde. © 1969, American Chemical Society. All rights reserved.
