Methanesulfonic anhydride is used to prepare methylsulfonyl esters called as mesylates. It finds application in the reaction of aromatic alkylation. It reacts with dimethylsulfoxide to get sulfoxonium complex, which is a useful oxidizing agent.
More powerful sulfonylating reagent than the sulfonyl chloride, also avoiding possible displacement of sulfonate by halide. With a catalytic amount of the acid effects mesylation of deactivated aromatics such as 1,3-dichlorobenzene: Chem. Lett., 395 (1988); mesyl chloride is ineffective.
Primary and secondary alcohols may be oxidized to carbonyl compounds by sulfonic anhydrides in DMSO: J. Org. Chem., 39, 1977 (1974). For related methods, see Dimethyl sulfoxide, A13280.
