Synthesis and reactivity of sulphinyldithioacetate and sulphonyldithioacetate esters and some related compounds

Abstract

(Methylsulphinyl)ketene dithioacetals (3) or alkyl (methylsulphinyl)dithioacetates (4), and (methyl-sulphonyl)ketene dithioacetals (16) or alkyl (methylsulphonyl)dithioacetates (17) were prepared from dimethyl sulphoxide and dimethyl sulphone, respectively. Then, bis-[2,2-bis(ethylthio)vinyl]sulphide, bis-[2,2-bis(ethylthio) vinyl] sulphoxide, and bis-[2,2-bis(methylthio)vinyl] sulphone were derived from (4) or (17). The reactivity of these compounds was examined.
