Ru(II)-catalyzed intermolecular ortho-CâH amidation of weakly coordinating aromatic ketones with sulfonyl azides is reported. The developed reaction protocol can be extended to various substituted aromatic ketones to afford a wide range of desired CâN bond formation products in good yields.

An efficient manganese-catalyzed ortho-C-H amidation of weakly coordinating aromaticketones using the readily available sulfonyl azide as the amination reagent is developed. The key step is the ketone directed aromatic metalation using the in situ generated reactive Mn intermediate, MnMe(CO)5. This method offers excellent chemical yields, high regioselectivities, and good functional group tolerance
