Sulfonimidoyl　fluorides,　the　aza-bioisostere　of　sulfonyl　fluorides,　are　emerging　as　a　promising　link　-age　agent　in　the　sulfur(VI)　fluoride　exchange　reaction　(SuFEx).　However,　conventional　synthetic　approaches　typically　require　the　use　of　either　unstable　sulfonimidoyl　chlorides,　toxic　and　corrosive　sulfur　fluorides,　or　expensive　electrophilic　fluorinating　agents.　Herein,　we　report　an　electrochemistry-en-abled　oxidative　nucleophilic　fluorination　of　readily　available　and　bench-stable　sulfinamides　using　a　com-mercially　available　and　easy-to-handle　triethylamine　trihydrofluoride.　With　other　nucleophilic　agents,　this　electrochemical　approach　also　serves　as　a　general　approach　to　diverse　sulfonimidoyl　derivatives,　including　sulfonimidoyl　azides　and　acetates.
