1, 4-Bis [1-(2-hydroxyethyl)-1 H-tetrazol-5-yl]-1, 4-dimethyl-2-tetrazene (12a), 1, 4-bis [1- isopropoxycarbonylmethyl-1 H-tetrazol-5-yl]-1, 4-dimethyl-2-tetrazene (12b), and 1, 4-bis [1- carboxymethyl-1 H-tetrazol-5-yl]-1, 4-dimethyl-2-tetrazene (13) have been synthesized as new nitrogen-rich compounds. The tetrazenes were obtained by oxidation of the corresponding tetrazolylhydrazines using bromine. Moreover, a new method to prepare ...
