Cyanamides are an important class of molecules. 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.

We developed a nitroxyl-catalyzed bromoesterification of alkenes with bromo reagents, which includes a six-membered ring bromolactonization of alkenyl carboxylic acids catalyzed by AZADO as the nitroxyl radical catalyst, and an intermolecular bromoesterification of alkenes with carboxylic acids using NMO as the N-oxide catalyst. We also accomplished a remote diastereoselective bromohydroxylation via an AZADO-catalyzed six-membered ring bromolactonization and a subsequent ring cleavage reaction with alkylamines to furnish ?-bromo-δ-hydroxy amides with high diastereoselectivity.
