The nitrogen content of tetrazolo[l,5‐b][1,2,4]triazine is 68.9%. It has a good application prospect in energetic material field. The synthesis was carried out, and the single crystal was cultivated. The analysis showed that the two rings of tetrazolo[l,5‐b][1,2,4]triazine are in the same flat, and the molecular accumulation displayed the net‐like structure in the space. The thermal decomposition process

Unsubstituted triazolo[4,3-b]- and tetrazolo[1,5-b],2,4-triazines react with carbanions generated from dimedone and barbituric acid to give adducts of a C-nucleophile with the heterocyclic system through the C=N double bond. The adducts can be oxidized under mild conditions into products of nucleophilic hydrogen substitution. Analogous adducts with carbanions produced in the reactions of ethyl cyanoacetate and ethyl malonate with (BuOK)-O-t proved to be unstable; in this case, the title azolotriazines immediately yield products of nucleophilic hydrogen substitution in position 7. Tautomerism of the S-N(H) products obtained is discussed.

3-Methylthio- and 3-amino-1,2,4-triazines react with resorcinol to give benzofurotetrahydrotriazine derivatives, while reactions of [1,2,4]triazolo[4,3-b]- and tetrazolo[1,5-b][1,2,4]triazines with resorcinol stop at the stage of resorcinol addition. According to the results of quantum-chemical calculations, the possibility for further cyclization of the resorcinol addition products is determined by the following factors: tautomeric and conformational states of the compounds, which ensure spatial proximity of the hydroxy group to the cyclization center (C-6); charges on the C-6 atom of the triazine ring and oxygen atom of the resorcinol fragment in the conformation most favorable for cyclization; and energies of the highest occupied and lowest unoccupied molecular orbitals of the resorcinol addition products.
