Abstract

Pyrazolo[4,5d]-1,2,3-triazoles and 3,4-dimethyl-1,6-diphenyl-dipyrazolo[4,5-b∶4′,5′- c]-1,6-dihydropyridazine, the structures of which are confirmed by the mass and PMR spectra, were isolated as side products in the preparation of macrocyclic compounds by the template synthesis of o-amino-o'-haloazopyrazoles. The PMR spectra of pyrazolo[4,5-d]-1,2,3-triazoles are examined in comparison with the PMR spectra of the corresponding noncyclic azopyrazoles. All of the compounds obtained were characterized by the results of elementary analysis and data from the IR, UV, mass, and NMR spectra.
