N2 is the only by‐product in a stereospecific and highly diastereoselective intramolecular CH amination of sulfamoyl azides with a cobalt(II)‐based metalloradical catalyst (see scheme). The catalytic system has an unusual capacity for the efficient amination of strong primary CH bonds, as well as secondary and tertiary CH bonds, and functional‐group tolerance is excellent owing to the neutral and
