In order to address the challenges associated with using sulfuryl fluoride (SO2F2) as a reagent, we considered using cheap commodity chemicals such as sulfuryl chloride (SO2Cl2) and potassium fluoride (KF) to generate SO2F2 in-situ. This approach was motivated by the greater thermodynamic stability of the S(VI)-F bond (~90 kcal/mol) compared to the S(VI)-Cl bond (~46 kcal/mol), which suggests that this exchange should be achievable . Our initial batch experiments using SO2Cl2 and KF in CH3CN confirmed the feasibility of this approach, demonstrating succesful conversion of first SO2Cl2 to SO2FCl and later to SO2F2 was achieved within two hours (see Supplementary Materials).
