A highly effective Co(II)-based system has been developed for catalytic intramolecular C—H amination with phosphoryl azides without the need of terminal oxidant or other additives, resulting in the high-yielding production of cyclophosphoramidates with nitrogen gas as the by-product; additional features of this new catalytic system include the amination of primary C—H bonds and formation of 7-membered ring structures.
