Abstract
This paper reports a convenient copper-catalyzed three-component conversion of arylhydrazine hydrochlorides to arenesulfonyl fluorides in good yields under mild conditions, using 1,4-diazabicyclo [2.2.2]octane bis(sulfur dioxide) (DABSO) as a sulfonyl source and N-fluorobenzenesulfonimide (NFSI) as a fluorine source based on a radical sulfur dioxide insertion and fluorination strategy. Notably, arylhydrazine hydrochloride is used as a safe precursor of aryl radicals.
