      abstract     = {Access to SuFExable compounds was remarkably simplified by
                      introduction of the solid FO2S-donor SuFEx-IT. However, the
                      published process for preparation of this reagent relies on
                      the use of sulfuryl fluoride (SO2F2), which is difficult to
                      obtain and highly toxic. Herein, we disclose a simple
                      protocol for SO2F2-free, hectogram-scale preparation of the
                      analogous desmethyl SuFEx-IT from inexpensive starting
                      materials. The reagent was prepared in a high $(85\%)$ total
                      yield and without chromatographic purification steps. In
                      addition, we demonstrate the utility of desmethyl SuFEx-IT
                      by successful preparation of a series of fluorosulfates and
                      sulfamoyl fluorides in high to excellent yields. As such,
                      our work recognizes desmethyl SuFEx-IT as a valuable
                      alternative to common FO2Sdonors and enables cost-efficient
                      access to substrates for SuFEx click chemistry.},
