An　environmentally　friendly　and　efficient　electrochemical　fluorosulfonylation　of　styrenes　has　been　developed.　With　the　use　of　sulfonylhydrazides　and　triethylamine　trihydrofluoride,　a　diverse　array　of　β-fluorosulfones　could　be　readily　obtained.　This　reaction　features　mild　conditions　and　a　broad　substrate　scope,　which　could　also　be　conveniently　extended　to　a　gram-scale　preparation.　©　2021　The　Royal　Society　of　Chemistry.
