A one-pot procedure for the direct introduction of sulfonyl fluoride groups into arenes from arylamines is developed using K2S2O5 and NFSI as the sulfur dioxide surrogate and fluorine source. It features mild and practical conditions and good functional group tolerance.
A one-pot procedure for the synthesis of arenesulfonyl fluorides from arylamine is developed with K2S2O5 and Nfluorobenzenesulfonimide (NFSI) as the sulfur dioxide surrogate and fluorine source, respectively. This method realizes the direct introduction of sulfonyl fluoride groups into arenes from abundant arylamines under transition-metal-free catalysis conditions, and features its mild and practical conditions and good functional group tolerance.
