title: Cobalt(II)-catalyzed intramolecular C-H amination with phosphoryl azides: formation of 6- and 7-membered cyclophosphoramidates.
abstract: 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 byproduct. Additional features of this new catalytic system include the amination of primary C-H bonds and formation of 7-membered-ring structures.
