A Pd and norbornene-catalyzed ortho-arene amination via Catellani-type C-H functionalization is reported. Aryl halides are used as substrates; N-benzoyloxyamines and isopropanol are employed as the amine source (oxidant) and reductant respectively. Examples are provided in 50-99% yields with high functional group tolerance. This method gives complementary site selectivity at the ortho-instead of ipso-position of aryl halides.
