REFERENCES

  • 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.
