In order to prepare specific 4-nitro-5-R-2-acetylthiophenes as intermediates for the synthesis of biologically active compounds, the authors have conducted an investigation of the nitra ion of 5-R-2-acetylthiophenes using fuming nitric acid (d = 1.5) in organic solvent media consisting of carbon tetrachloride, 1,2-dichloroethane, and acetonitrile. The nitration using fuming nitric acid at elevated temperatures leads to the formation of 3,4-bis (5-R-2-thienoyl) furoxans, rather than the expected heterocycle-nitrated derivatives. The structure of 3,4bis (2-thienoyl) furoxan was established by x-ray structural analysis.
