Аннотация

The reaction of 6-nitro-7-oxo-4,7-dihydroazolo[5,1-c]-1,2,4-triazines with O-, N-, and S-nucleophiles leads to the corresponding 6-substituted compounds. In the reaction of 2,4-dimethyl-6-nitro-7-oxo-4,7-dihydro-1,2,4-triazolo[5,1-c][1,2,4]triazine with hydrazine hydrate, 3-methyl-5-(N-methylamino)-1,2,4-triazole is formed.
