General description
Dimethyl sulfoxide (DMSO) is a high-boiling polar aprotic solvent and mild oxidant used in organic synthesis. DMSO can also act as a one-carbon synthon in organic chemistry. It is a source of -Me, -SMe, -SO2Me functional groups. It is also used as a versatile reagent in Pfitzner-Moffatt oxidation, Swern oxidation, and Corey-Chaykovsky reaction.
