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
A highly efficient method for the synthesis of aryl sulfonyl fluorides was developed from aryl sulfonyl chlorides using SO2F2 as fluoride source in up to 98% isolated yield under mild conditions. Gram scale experiments were also conducted, revealing the good practicality of this new protocol.
