This approach involves a tandem nucleophilic addition of alkylamines to hydrazonoyl cyanides and in situ oxidative cyclization of the resulting 2-(aryl-azo)ethene-1,1-diamines in the presence of copper(II) acetate and air. The described one-pot procedure is characterized by good yields, excellent selectivity, methodical simplicity, and uses readily available chemicals. This method was applied to the gram-scale synthesis of 2-aryl-1,2,3-triazoles. Доп.точки доступа: Gavlik, K. D; Lesogorova, S. G.; Sukhorukova, E. S.; Subbotina, J.O.; Slepukhin, P.
