The elaborate cobalt(II)-porphyrin catalyst [Co(Pl)] further enabled intramolecular amination of C(sp )-H bonds in simple alkyl chains, adjacent to electron-withdrawing groups, or at the allylic or propargylic positions through decomposition of sulfamoyl azide (Scheme 10.21) [50]. Thus, the catalyst promotes nitrene insertion into such C(sp )-H bonds located at the y-position of the sulfamoyl group to afford six-membered cyclic sulfamides in excellent yields, which serve as versatile 1,3-diamine scaffolds. On the basis of mechanistic experiments, a mechanism that is distinct from related Rh -catalyzed C-H amination was proposed. Thus, the 15-electron metalloradical catalyst [Co(Pl)j decomposes the sulfamoyl azide to form a Co -radical nitrene species, which...
