Abstract

Sulfamides are known for their biological activity. 5 They are also used as chelating agents 6 and in self-assembly. 7 Symmetric N,N′-sulfamides are typically prepared by reactions of amines with sulfuryl chloride. 8 However, the latter reagent is made from SO 2 . Moreover, only dialkylsulfamides can be obtained in reasonable yields from this procedure. 9 Reactions with aromatic amines mostly give complex mixtures, containing chlorination and oxidation products. We found ...
