| Abstract: | The nitration of trans-2-styrylthiophene in carbon tetrachloride, nitroethane and acetic anhydride has been investigated. The nitration products were: β-nitro-2-styrylthiophene as the main product with 3-nitro-2-styrylthiophene and the 5-nitro isomer in smaller amounts. They were identified by the chromato-graphic and spectroscopic (uv and nmr) comparison with the reference compounds. The isomer percentages, determined by glc, were unchanged under different nitration conditions (time, temperature and molar ratio), but were dependent on the solvent used. |
