1,2,3,4-Tetrazine 1,3-dioxides annulated with 1,2,3-triazoles and 1,2,3-triazole 1-oxides have been synthesized by the reaction of 4-amino-5-(tert-butyl-NNO-azoxy)-2-R-2H-1,2,3-triazoles (R=Me, i-Pr, t-Bu) and their 1-oxides (R=H, Me, Et, i-Pr) with the HNO3/H2SO4/Ac2O system. Their thermal stability, spectroscopic, and X-ray properties have been studied.

A novel approach for the synthesis of 6-(tert-butyl-NNO-azoxy)-5-methylthio-1,2,3,4-tetrazine 1,3-dioxide (1) was developed. This compound is likely to be a precursor of tetrazino-tetrazine 1,3,6,8-tetraoxide. The synthetic strategy consists of four steps: a synthesis of bis(tert-butyl-NNO-azoxy)methane, coupling of the latter with dimethyl nitrodithioimidocarbonate to give N-nitroimine 3, O-alkylation
