Sulfamates and sulfamides were most often synthesized from alcs. and amines with sulfamoyl chloride, which was an unstable reagent. Hexafluoroisopropyl sulfamate (HFIPS) as a bench-stable solid that reacts readily with a wide variety of alcs., amines, phenols, and anilines under mild reaction conditions was identified. The sole byproduct of the reaction was hexafluoroisopropanol (HFIP) and reaction products was often isolated in high purity after an aqueous workup (optional) and removal of solvents by evaporation
