Thionation of Chalcone and Aurone Derivatives by Lawesson's Reagent
摘要:
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.

ABSTRACT Phenanthrenequinone 2 and aurones 5a–h are potentially capable of undergoing an interesting photochemicalreaction leading to the formation of the adducts 6a–h. The structures of the 1,4-dioxine derivatives 6a–h were firmly established on the basis of analytical data and spectroscopic evidences.
