A series of thiiranes react with benzyne to provide an efficient synthesis of phenyl vinyl sulfides. The reaction is stereospecific, thus producing cis-(phenylthio)-stilbene from cis-2,3-diphenylthiirane and trans-(phenylthio)stilbene from trans-2,3-diphenylthiirane.

For the first time, episulfones have been prepared by oxidation of the corresponding episulfides. Seven examples are given, most of which proceed in good to excellent yield. The first oxidation of an episulfoxide to an episulfone is also reported as part of a preliminary mechanistic study.

A convenient and stereoselective synthesis of episulfides based on the reaction of readily available S-(β-oxoalkyl) thiophosphate with sodium borohydride and their conversion into alkenes is described.
3,4-Dihydro-1,2,5-benzotrithiepin, 6H-2,3-dihydro-1,4,5-benzotrithiocin, and these derivatives were conveniently synthesized in good yields upon treating 1,2-benzenedithiol and 2-mercaptomethylbenzenethiol with various thiiranes in the presence of triethylamine in a polar solvent.
