AbstractThe catalytic (C/Pd) hydrogenation of 3-arylamino-2-nitro-2-enones (1) in the presence of carboxylic ortho esters (2) affords 4-acyl-1-arylimidazoles (3) in yields (20–70%) which depend on the degree of substitution of the imidazole ring. The spectral properties of compounds 3, and particularly the 13C-nmr spectra, reflect both the electronic and steric effects of the substituents on the π-electron delocalization and planarity of the bicyclic system.
