Dixanthogen disulfides are a class of
organosulfur compounds with the formula (ROC(S)S)2. Usually yellow solids, they are the product of the oxidation of
xanthate salts.[1] A common derivative is
diethyl dixanthogen disulfide. Diisopropyl dixanthogen disulfide is commercially available. They are structurally related to
thiuram disulfides.
Uses and reactions
Diethyl dixanthogen disulfide is a component for
froth flotations used, inter alia, for the separation of sulfide minerals like
pyrrhotite. Diisopropyl dixanthogen disulfide is a
reagent in the synthesis of sulfur
heterocycles.[2]
Dialkoxy dixanthogen disulfides undergo desulfurization by cyanide to give bis(alkoxythiocarbonyl)sulfides:[3]
