Abstract

Sulfoxides are compounds that contain a sulfinyl group covalently bonded at the sulfur atom to two carbon atoms. Sulfoxides represent an intermediate oxidation level between sulfides and sulfones. The naturally occurring sulfoxides often are accompanied by the corresponding sulfides or sulfones. The only commercially important sulfoxide is the simplets member, dimethyl sulfoxide.

Sulfoxides occur widely in small concentrations in plant and animal tissues. Properties, synthesis and manufacture, health and safety factors, and uses are discussed.
