The synthesis and chlorinolysis of 5-phenyl-2,4,5-trithiapentane-2,2-dioxide

Abstract

Application of mercaptide anions to the dechlorination of an α-polychlorosulfonyl substrate has provided the key step in a successful synthesis of the title compound. 5-Phenyl-2,4,5-trithiapentane-2,2-dioxide undergoes chlorinolysis in an aqueous medium to yield products consistent with the view that α-sulfonyl oxodichlorosulfonium chlorides and α-sulfonyl dichlorosulfonium chlorides may undergo unusually facile Pummerer rearrangements.
