A new approach to the synthesis of 2 H‐benzotriazoles is described. This strategy is based on the copper‐catalyzed CN coupling of 2‐haloaryltriazenes or 2‐haloazo compounds with sodium azide and the intramolecular addition of nitrene to NN bonds. This approach allows the synthesis of various N‐amino‐ and N‐aryl‐2 H‐benzotriazoles in water, in good to excellent yields. The procedure is simple and
