Thiosulfonate

Thiosulfonate esters are organosulfur compounds with the formula. The parent member S-methyl methanethiosulfonate is a colorless liquid.
Thiosulfonate esters are usually produced by oxidation of disulfides or the nucleophilic attack of thiolates on organosulfonyl halides. The simplest thiosulfonate, can however be prepared from dimethyl sulfoxide by treatment with oxalyl chloride.
Thiosulfonate also refers to the thiosulfonate anion and its salts. Alkali metal organylthiosulfonates are the salts of organylthiosulfonic acids. They are prepared by the reaction of organosulfonyl chlorides with sources of sulfide.
Oxidation with mCPBA gives disulfones.
