CAS 2179072-33-2, Cat. No EN300-6734306
Donor of F-SO2+ moiety

A fluorosulfuryl imidazolium salt

SuFEx-IT is click-chemistry reagent that is a much safer analog of SO2F2 gas, that offers more simple procedure and less hazard to health. Even more, SuFEx-IT possesses greater reactivity, selectivity compere to SO2F2. The F-SO2+ fragment attaches to H-containing acceptor groups such as phenols and amines to give fluorosulfates and sulfoamoyl fluorides respectively with good yields.

Synonyms: 1-(fluorosulfonyl)-2,3-dimethyl-1H-imidazol-3-ium trifluoromethanesulfonate, Fluorosulfuryl imidazolium salt
