Sulfone

Sulfone

A sulfone is a chemical compound containing a sulfonyl functional group attached to two carbon atoms. The central sulfur atom is twice double bonded to oxygen and has two further hydrocarbon substituents. The general structural formula is R-S(=O)(=O)-R' where R and R' are the organic groups. The use of the alternative name sulphone is discouraged by IUPAC. Sulfides are often the starting materials for sulfones by organic oxidation through the intermediate formation of sulfoxides. For example dimethyl sulfide is oxidized to dimethyl sulfoxide and then to dimethyl sulfone.

In the Ramberg-Bäcklund Reaction and the Julia olefination sulfones are converted to alkenes.

Examples of sulfones include dapsone, a drug formerly used as an antibiotic to treat leprosy, dermatitis herpetiformis, tuberculosis, or pneumocystis pneumonia (PCP).
