Abstract
⺠cis-trans isomerism of 5-substituted 2-acetylthiophenes was analyzed and quantified. ⺠Theoretical calculations were performed for isolated state and solutions (IEFPCM). ⺠A close agreement between infrared data and theoretical calculations was obtained. ⺠Low temperature C-13 NMR spectra confirmed the low energy barrier (â¼8 kcal molâ1).
