The preparation of 2-substituted 1-(5-nitro-2-thienyl)-ethylenes based on the reaction of (Z)-2-bromo-1-(5-nitro-2-thienyl)ethylene with aromatic or heteroaromatic compounds in the presence of aluminum chloride is described. The structure of the derivatives prepared was investigated by means of 1H NMR and UV spectra and dipole moments measurement.
