A catalytic and step economic protocol for the construction of N-2-aryl-naphthotriazoles via copper-catalyzed cyclization of aryl amines and aryldiazonium salts is reported. With dioxygen in the air as termial oxidants under copper catalysis, various N-2-aryl-naphthotriazoles were synthesized in high yields. Importantly, this protocol features the sufficient inhibition of the classic C-N2 bond cleavage process of aryldiazonium tetrafluoroborates under copper catalysis and the undesired dehydrogenative coupling of aryl amines under oxidative conditions. Preliminary mechanistic studies indicated that a radical procedure might not be involved in this transformation. In addition, simple decoration of the obtained compounds delivers novel and attractive tetraphenylethylene moiety containing N-2-aryl-naphthotriazole derivatives. (Figure presented.).
