An intramolecular palladium-catalyzed cross-dehydrogenative C-H amination under blue LED irradiation at room temperature was developed. With oxygen as the external oxidant, a broad range of functional groups was compatible with the aromatic C-H amination of 2-amino-3-arylnaphthalene-1,4-diones, and diverse carbazolequinones can be obtained with good yields and excellent regioselectivity.
