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.
Die Titelverbindung (IV) wird ausgehend vom Sulfid (I) über die Stufen (IIa) und (IIb) (durch Umsetzung von (IIa) mit Methanol) synthetisiert; ihre Chlorolyse in wäßrigem Medium zu den Produkten (V) und (VI) wird eingehend mechanistisch interpretiert.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
