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 and tosylate salts/acids.

通过消除轻松制备双（硫代羰基）二硫化物

提出了一种鲁棒的，易于合成的双（硫代羰基）二硫化物的制备方法。该路线遵循消除机制，而不是更常见的氧化。的另外p甲苯磺酰氯于硫代羰基硫醇盐导致消除的氯化物通过三硫代碳酸酯阴离子和甲苯磺酰的离去基团的随后消除（由第二硫代羰基硫醇盐）。反应的副产物是双（4-甲基苯基）二砜和甲苯磺酸盐/酸。
