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 ...
Deuterated DMSO, also known as dimethyl sulfoxide-d 6, is an isotopologue of dimethyl sulfoxide (DMSO, (CH 3) 2 S=O)) with chemical formula ((CD 3) 2 S=O) in which the hydrogen atoms ("H") are replaced with their isotope deuterium ("D"). Deuterated DMSO is a common solvent used in NMR spectroscopy.
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 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.
An investigation by Lawrence Livermore National Laboratory suggested that Ramirez had been self-administering dimethyl sulfoxide (DMSO) as a pain treatment. The oxygen from the mask provided by paramedics during her transport to the hospital likely converted the DMSO into dimethyl sulfate (DMS), a highly toxic and carcinogenic alkylating agent.

Sulfonamides can be prepared in the laboratory in many ways. The classic approach entails the reaction of sulfonyl chlorides with an amine. [citation needed] RSO 2 Cl + R' 2 NH → RSO 2 NR' 2 + HCl. A base such as pyridine is typically added to absorb the HCl that is generated. Illustrative is the synthesis of sulfonylmethylamide. [3]
In these oxidations, care is required to avoid over oxidation to form the sulfone. For example, dimethyl sulfide is oxidized to dimethyl sulfoxide and then further to dimethyl sulfone. Unsymmetrical sulfides are prochiral, thus their oxidation gives chiral sulfoxides. This process can be performed enantioselectively. [9] [10]
