The Swern oxidation, named after Daniel Swern, is a chemical reaction whereby a primary or secondary alcohol is oxidized to an aldehyde or ketone using oxalyl chloride, dimethyl sulfoxide (DMSO) and an organic base, such as triethylamine.[8][9][10] The reaction is known for its mild character and wide tolerance of functional groups.[11][12][13][14]
