The　invention　of　versatile　linkage　agents　provides　the　chemical　basis　for　SuFEx　chemistry.　Sulfonimidoyl　fluorides　and　sulfondiimidoyl　fluorides　are　aza-isosteres　of　sulfonyl　fluorides　with　diverse　reactivity　through　the　fine-tuning　of　N-substituents.　However,　limited　synthetic　approaches　impede　their　wide　applications　in　SuFEx　chemistry.　Herein,　we　develop　a　straightforward　electrochemical　strategy　for　sulfonimidoyl-　and　sulfondiimidoyl　fluorides　through　sequential　oxidations　of　the　readily　available　sulfenamides　via　sulfinamide　and　iminosulfinamide　intermediates,　respectively.　The　previously　rarely　investigated　(bis)sulfondiimidoyl　fluorides　are　now　easily　accessible　and　readily　participate　in　SuFEx　chemistry　with　diverse　oxygen　and　nitrogen　nucleophiles,　macrocyclization,　and　polymerization.　©　2025　The　Authors.　Published　by　American　Chemical　Society.
