Synthesis of Sulfamides
The combination of calcium triflimide and DABCO activates sulfamoyl fluorides, fluorosulfates, and sulfonyl fluorides for SuFEx with amines to provide a diverse set of sulfamides, sulfamates, and sulfonamides at room temperature under mild conditions.

N-(tert-Butoxycarbonyl)-N-[4-(dimethylazaniumylidene)-1,4-dihydropyridin-1-ylsulfonyl]azanide allowed sulfamoylation of amines under very mild conditions to give sulfamide derivatives in good yields.
