The oxidation process of dimethyl sulfoxide DMSO follows the classic path of "electrophilic activation-nucleophilic addition-elimination": First, electrophilic reagents (such as oxalyl chloride, DCC, sulfur trioxide-pyridine complex) bind to the sulfur-oxygen double bond of DMSO, activate the oxygen atom to make it easier to leave, and generate the key intermediate sulfonium cation.
