ABSTRACT

According to the 1H and 13C NMR data, the molecule of 2-(2-benzoylethenyl)-1-vinylpyrrole has a nearly planar structure with trans arrangement of the vinyl and oxovinyl groups. The unsaturated fragments give rise to effective conjugation. The vinyl group in 5-substituted 2-(2-acylethenyl)-1-vinylpyrroles strongly deviates from the heteroring plane because of steric effect of the substituent; however, this effect does not change the arrangement of the other unsaturated fragments.
