Triphenyl imidazole synthesis
WebThe 2,4,5-triphenylimidazole was synthesized by refluxing benzoin, benzaldehyde and ammonium acetate in equimolar quantities. The Mannich bases were synthesized by … WebDue to their great importance, many synthesis strategies have been developed. In 1882, Radziszewski and Jap reported the first synthesis of the imidazole from 1,2- dicarbonyl compound, various aldehydes and ammonia, to obtain the 2,4,5-triphenyl imidazoles. Also, Grimmett et al proposed the synthesis of the imidazole using nitriles and esters.
