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.
The crude dimethyl sulfide product was purified by distillation and could then be used to produce DMSO. When Gaylord closed its Bogalusa plant in 2010, it changed its process technology to manufacture DMS from methanol and hydrogen sulfide gas via gas phase thioetherification. This is the dominant method used worldwide to make DMS and there are ...
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.

All such derivatives feature O-bonded sulfoxides. The tricationic complex in [Rh(dmso) 6](O 3 SCF 3) 3 features one S-bonded and five O-bonded sulfoxide ligands. [10] The complex [Cu(Ph 2 SO) 4] 2+ is square planar, in contrast to the derivative with dmso ligands. The square planar d 8 complex [Rh(dmso) 4] + features a pairs of S- and O-bonded ...
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] Symmetrical sulfoxides can be formed from a diorganylzinc compound and liquid sulfur dioxide. [11]
