is a chemical compound
containing a sulfonyl functional group
attached to two carbon atoms. The central sulfur
atom is twice double bonded
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
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).
