| Abstract: | Abstract A series of 1-(pyrimidin-2-yl)hydrazine-1-carbonitriles was synthesized by base-catalyzed condensation of 3,4-diamino-1,2,4-triazole
hydrobromide with several 1,3-dinucleophilic compounds. These final products were formed by ring opening of the 1,2,4-triazolium
ring via intermediate 3-amino1,2,4]triazolo1,5-a]pyrimidinium bromides. |
