Sulfonyl　fluorides　have　widespread　applications　in　many　fields,　including　organic　synthesis,　chemical　biology,　drug　discovery　and　materials　science.　In　particular,　in　the　past　decade,　a　number　of　aliphatic　sulfonyl　fluorides　have　been　identified　showing　various　biological　activities.　These　applications　and　appealing　features　of　sulfonyl　fluorides　have　brought　about　a　significant　advancement　in　developing　synthetic　methods　to　access　sulfonyl　fluorides.　In　this　review,　we　will　discuss　the　recent　developments　of　radical　approaches　for　the　synthesis　of　aliphatic　sulfonyl　fluorides.
