We have studied thionylation of 5-R-3H-furan-2-ones and 4-oxoalkanoates using phosphorus pentasulfide and the Lawesson reagent. It was found that the structure of the reaction products dependent on the thionylating agent. Preparative methods have been developed for the synthesis of 5-R-5H- and 5-R-3H-thiophen-2-ones and 5-R-3H-furan-2-thiones.
