| Abstract: | Abstract The reaction of Lawesson's reagent (LR 5) with chalcones (4a–h) and aurones (12a–h) proceeds in refluxing toluene to give the respective benzofuranylprop-2-en-1-thiones (8a–h) and benzodifuran-3-thiones (13a–h). Correct elemental analyses and spectroscopic data were obtained for the new compounds. |
