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 sulfonium oxidations can be categorized into two groups: The methods discovered earliest rely on activated alcohols like alkyl tosylates (Kornblum oxidation) [2] or alkyl chloroformates (from reaction of alcohols with phosgene: Barton-Kornblum) [3] that react as electrophiles when treated with DMSO, liberating an oxygenated leaving group (e.g. OTs−).
Many horse liniment formulas in diluted form have been used on humans, though products for horses which contain DMSO are not suitable for human use, as DMSO carries the topical product into the bloodstream. [18] Horse liniment ingredients such as menthol, chloroxylenol, or iodine are also used in different formulas in products used by humans. [19]
In organic chemistry, the Swern oxidation, named after Daniel Swern, is a chemical reaction whereby a primary or secondary alcohol (−OH) is oxidized to an aldehyde (−CH=O) or ketone (>C=O) using oxalyl chloride, dimethyl sulfoxide (DMSO) and an organic base, such as triethylamine.
The Parikh–Doering oxidation is an oxidation reaction that transforms primary and secondary alcohols into aldehydes and ketones, respectively. [1] The procedure uses dimethyl sulfoxide (DMSO) as the oxidant and the solvent, activated by the sulfur trioxide pyridine complex (SO 3 •C 5 H 5 N) in the presence of triethylamine or diisopropylethylamine as base.
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 ...
