Cyanamides are an important class of mols. This work describes a facile synthesis of disubstituted cyanamides. Here, readily accessible 1-cyano-1,2-benziodoxol-3-(1H)-one (CBX) was applied as a stable electrophilic cyanation reagent. Diverse secondary amines were effectively cyanated. Moreover, secondary sulfonamides proved to be suitable substrates and were readily converted to N-alkyl(aryl)-N-arylsulfonyl-cyanamides, as the significant building blocks of the organic transformation.
