Dimethyl sulfone (DMSO 2) is an organosulfur compound with the formula (CH 3) 2 SO 2. It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). [4] This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert ...
Impure dimethyl sulfate was prepared in the early 19th century. [4] J. P. Claesson later extensively studied its preparation. [5] [6]It was investigated for possible use in chemical warfare in World War I [7] [8] in 75% to 25% mixture with methyl chlorosulfonate (CH 3 ClO 3 S) called "C-stoff" in Germany, or with chlorosulfonic acid called "Rationite" in France.

Desulfonylation reactions are chemical reactions leading to the removal of a sulfonyl group from organic compounds.As the sulfonyl functional group is electron-withdrawing, [1] methods for cleaving the sulfur–carbon bonds of sulfones are typically reductive in nature.
Dimethyl sulfide is considered the most important thioether produced industrially. One major use is for the production of borane dimethyl sulfide from diborane: [19] B 2 H 6 + 2 (CH 3) 2 S → 2 BH 3 ·S(CH 3) 2. Oxidation of dimethyl sulfide gives the solvent dimethyl sulfoxide. Further oxidation affords dimethyl sulfone.
Sodium methylsulfinylmethylide (also called NaDMSO or dimsyl sodium) is the sodium salt of the conjugate base of dimethyl sulfoxide. This unusual salt has some uses in organic chemistry as a base and nucleophile. Since the first publication in 1965 by Corey et al., [2] a number of additional uses for this reagent have been identified. [3]
Organosulfur chemistry is the study of the properties and synthesis of organosulfur compounds, which are organic compounds that contain sulfur. [1] They are often associated with foul odors, but many of the sweetest compounds known are organosulfur derivatives, e.g., saccharin.
