N-arylbenzotriazoles leads respectively to indoles and carbazoles. Because the very rapid access to libraries of triazoles, for example by the copper-catalyzed [3+2] cycloaddition between alkynes and azides, this reaction allows the preparation of indoles in a single operation, by the simultaneous photolysis of the precursor library. As an example of such a synthesis of carbazoles, we prepared for the first
