The reactivity of the new 1,2,3-triazole-substitutedvinamidines ( i.e. 1-azabutadienes) was investigated. They were used as synthons to obtain new pyrazole, di-1,2,3-triazole as well as 4- amino-1,2,3-triazole derivatives. The Diels-Alder reaction with inverse electronic demand (using dimethyl 1,2,4,5-tetrazin-3,6-dicarboxylate as reagent) resulted in the formation of a new pyridazine derivative.
