A robust facile synthetic preparation of bis (thiocarbonyl) disulfides is presented. The route follows an elimination mechanism rather than the more common oxidation. Addition of p- tosyl chloride to a thiocarbonyl thiolate results in the elimination of the chloride by the trithiocarbonate anion and subsequent elimination of the tosyl leaving group (by a second thiocarbonyl thiolate). The side products of the reaction are bis (4-methylphenyl) disulfone ...
