A rhodium(III)‐catalyzed C−H amination of benzamides and isoquinolones with anthranils has been realized under assistance of weakly coordinating amide, leading to a bifunctionalized amination product which can further cyclize to acridine under in situ or ex situ conditions.

Cooperative cobalt- and copper-catalyzed C-H activation of imidate esters and oxidative coupling with anthranils allowed efficient synthesis of 1H-indazoles in the absence of metal oxidants. The anthranil acts as a convenient aminating reagent as well as an organic oxidant in this transformation. The copper catalyst likely functions at the stage of N-N formation.
