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.
13 C NMR Spectrum of DMSO-d 6. Pure deuterated DMSO shows no peaks in 1 H NMR spectroscopy and as a result is commonly used as an NMR solvent. [2] However commercially available samples are not 100% pure and a residual DMSO-d 5 1 H NMR signal is observed at 2.50ppm (quintet, J HD =1.9Hz). The 13 C chemical shift of DMSO-d 6 is 39.52ppm (septet ...
cis-RuCl 2 (dmso) 4, a representative metal complex of a sulfoxide. Three DMSO ligands are S-bonded to Ru, one is O-bonded. Sulfoxides, especially DMSO, form coordination complexes with transition metals. Depending on the hard-soft properties of the metal, the sulfoxide binds through either the sulfur or the oxygen atom. The latter is ...

How long can my food last in the fridge after a power outage? Experts say it depends on the product, and whether it's in a refrigerator or freezer. Kaitlin Reilly. September 27, 2024 at 1:08 PM.
In the table above, it can be seen that water is the most polar-solvent, followed by DMSO, ... This page was last edited on 18 October 2024, at 19:14 (UTC).
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 ...
NaDMSO condenses with esters (1) to form β-ketosulfoxides (2), which can be useful intermediates. [9] Reduction of β-ketosulfoxides with aluminium amalgam gives methyl ketones ( 3 ). [ 10 ] Reaction with alkyl halides followed by elimination gives α,β-unsaturated ketones ( 4 ). β-ketosulfoxides can also be used in the Pummerer ...
