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 ...
The structure of a sulfone Dimethyl sulfone, an example of a sulfone. In organic chemistry, a sulfone is a organosulfur compound containing a sulfonyl (R−S(=O) 2 −R’) functional group attached to two carbon atoms.
Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH 3) 2 S O. This colorless liquid is the sulfoxide most widely used commercially. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.
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.
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.
The bond dissociation energies for dimethyl sulfide and dimethyl ether are respectively 73 and 77 kcal/mol (305 and 322 kJ/mol). Sulfides are typically prepared by alkylation of thiols. Alkylating agents include not only alkyl halides, but also epoxides, aziridines, and Michael acceptors. [6] They can also be prepared via the Pummerer ...
