Sulfurimidoyl difluorides (RNSOF2) are excellent multidimensional SuFEx hubs, however their preparation from the scarcely available thionyltetrafluoride (SOF4) gas limits this chemistry. Here, we propose silver pentafluorooxosulfate (AgOSF5) as a viable alternative to SOF4. Prepared by the AgF2-mediated oxidation of SOCl2, we found that the adduct produces sulfurimidoyl fluorides in high yields from
