Abstract β-Sulfonylacrylate phenyl and t-butyl thioesters, and β-sulfonylvinyl ketones have been prepared by oxidation of the corresponding β-aryl-and β-alkyl-thio compounds. In one case the β-sulfonylvinyl ketone was obtained from an epoxy sulfone. The β-aryl-and β-alkyl- thio compounds were obtained by chlorination-dehydrochlorination of saturated precursors. The reactions of 3-(phenylthio) propionyl chloride with organocadmium and Grignard ...
