The Swern oxidation is a modern method of converting primary or secondary alcohols to aldehydes or ketones using oxalyl chloride, dimethyl sulfoxide ( DMSO).
The Swern Oxidation of alcohols avoids the use of toxic metals such as chromium, and can be carried out under very mild conditions. This reaction allows the preparation of aldehydes and ketones from.

Swern oxidation is widely used to convert alcohols into their corresponding carbonyl compounds. However, the conventional method with use.
This oxidation proceeded conveniently by refluxing the alcohol in dimethyl sulfoxide and was facilitated by passing a stream of air through the reaction medium. The reaction stopped at the aldehyde stage.
The synthesis and arrested oxidation of amorphous cobalt nanoparticles using DMSO as a functional solvent – This synthesis method demonstrates that Co nanoparticles can be successfully synthesized by simply using DMSO as a functional solvent, thereby avoiding excessive oxidation and agglomeration in.
Until now, models considering only the oxidation in the gas phase describe merely the oxidation.
