Abstract
4-azido-2 H- 1,2,3-triazoles were synthesized by reaction of dichlorodiazadienes (which were synthesized from nitrobenzaldehyde ) with NaN3. It was established that during the reaction, unstable bis-azides are formed as a result of the replacement of geminal chlorine atoms at the double bond with azide anion. Then, the corresponding 1,2,3-triazoles were obtained as a result of elimination of nitrogen and intramolecular cyclization reaction. This method can be considered a highly effective method of synthesis for obtaining biologically active 4-azido-2H-1,2,3-triazoles. The structure of the synthesized compounds was confirmed by NMR and X-ray method.
