title: Palladium-catalyzed direct ortho-nitration of azoarenes using NO2 as nitro source.
abstract: A palladium-catalyzed direct ortho-nitration reaction of azoarenes was developed in which NO2 was used as both nitro source and oxidant for the first time. The nitration products were converted into o-aminoazoarenes or benzotriazole derivatives by a simple reduction.
