Ru(II)-Catalyzed C-H Amination of 1,2,3-Benzotriazinones with Azide Compounds.

A Ru(II)-catalyzed directed C-H amination of 1,2,3-benzotriazinones with azide compounds has been reported. The reaction has a wide substrate scope of organic azides with good results and represents a useful pathway to the construction of versatile heterocyclic amino products. In addition, the method can be used for the phthalazinones, highlighting the synthetic practicability of the strategy.
