Swern oxidation is a type of chemical reaction that occurs in chemistry. It takes a primary alcohol and converts it to a ketone or aldehyde using DMSO or COCI2, along with an organic base.
An Anglicized version of the interchange is something like the following:"Would you like a beverage?""No thank you; I wouldn't."ninguno--APEX
Swern oxidation mechanism goes through the formation of Dimethyl chloro sulphonium ion from oxalyl chloride and DMSO. Then that ion reacts with alcohol to form alkoxy sulfonium ion. Deprotonation of this intermediate gives a sulphur ylide, which undergoes intramolecular deprotonation via a five-membered ring transition state and fragmentation to yield the product(carbonyl compound) and DMS (odour!):
Primary or secondary alcohols can be used to prepare ketones through oxidation reactions. Common methods include using mild oxidizing agents like chromic acid, PCC (pyridinium chlorochromate), or Swern oxidation. Tertiary alcohols cannot be oxidized to ketones.
