IMPROVED SYNTHESIS AND THERMOCHEMICAL PROPERTIES OF AMINO- AND HYDRAZINO-1,2,4,5-TETRAZINES

Abstract

Improved protocols for the synthesis of 3,6-diamino- and 3,6-dihydrazino-1,2,4,5-tetrazines as well as 6-amino[1,2,4]triazolo[4,3-b][1,2,4,5]tetrazine were developed. Combustion energies were determined by the bomb calorimetry and the enthalpies of formation in the standard state were calculated for the compounds of this study. Based on the obtained data, the contribution of the 1,2,4,5-tetrazine moiety to the enthalpy of combustion of its derivatives was estimated.
