dixanthogen disulfide dixanthogen disulfide 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. a common derivative is diethyl dixanthogen disulfide. diisopropyl dixanthogen disulfide is commercially available. they are structurally related to thiuram disulfides. structure of diethyl dixanthogen disulfide. 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. dialkoxy dixanthogen disulfides undergo desulfurization by cyanide to give bis(alkoxythiocarbonyl)sulfides: (roc(s)s)2 + cn− → (roc(s))2s + scn− dixanthogens are also ectoparasiticides.
