Among the various SuFEx hubs, the -SO2F moiety has received significant attention due to its unique biophysical properties and its potential as a versatile connector between nucleophilic entities . One method for installing this moiety is the use of gaseous sulfuryl fluoride (SO2F2), which has been demonstrated for various organic molecules by the group of Sharpless . However, despite its potential as an economic and traceless compound, its mild toxicity and difficulty to handle have motivated researchers to seek for more practical alternatives. While in-situ generation of SO2F2 from 1,1'-sulfonyldiimidazole (SDI, Figure ) or the use of solid reagents such as phenyl]imidodisulfuryl difluoride (AISF) or 1-(fluorosulfonyl)-2,3-dimethyl-1H-imidazol-3-ium trifluoromethanesulfonate (FDIT) have been explored, these alternatives still require the use of SO2F2 in their preparation and produce unnecessary by-products. Hence, it is clear that these methods go against the principles of click chemistry and represent a challenge to date . Addressing these challenges by developing a new strategy for producing and dosing SO2F2 in a safe and controlled manner from simple chemicals would represent a significant advance in the field of SuFEx chemistry. Furthermore, such a process would significantly reduce the number of synthetic steps needed for SuFEx handle installation and therefore streamline the overall process.
