A one-stage synthesis of 1-acyl-l-nitro-2-furyl(thienyl)ethenes was developed and structural assessment of the products was performed by means of H-1, IR, and UV spectroscopy and dipole moment measurements. The acetyl derivatives have Z configuration, and the benzoyl derivatives, E configuration. The UV and IR spectra, as well as the rather high dipole moments (musimilar to5similar to6 D) point to an essential contribution in the structures of dipolar forms.
