Room-Temperature Cu(II)-Catalyzed Aromatic C—H Azidation for the Synthesis of ortho-Azido Anilines with Excellent Regioselectivity.

Cu(II)-catalyzed aromatic C–H azidation with azido-benziodoxolone under mild conditions has been described. The primary amine exhibits an excellent ortho-directing effect, providing ortho-azidated anilines as the sole products.
