From: A practical fluorosulfonylating platform via photocatalytic imidazolium-based SO2F radical reagent
All reactions were carried out with olefins 5 (0.10 mmol), IMSF salt 2(0.20 mmol, 2.0 equiv), fac-Ir(d-F-(p-t-Bu)ppy)3 (2 mol%) and cyclohexa-1,4-diene (1.5 equiv) in 2-methyltetrahydrofuran:Acetone = 9:1 (1 mL) under Ar and 60 W blue LEDs. a.IMSF reagent 2a was used. b.IMSF reagent 2b was used.
