A series of 1,3‐diazocyclopentane based energetic materials were synthesized and their properties were investigated. Compounds 5 and 6 were finally selected as promising candidates for high energy density materials and their frontier molecular orbitals, electronic densities, and electrostatic potentials were simulated

Improved reaction conditions for the preparation of octahydro-5-imino-2-(nitroimino)imidazo[4,5-d]imidazole (3) from 4,5-dihydroxy-2-nitroiminoimidazolidine (2) and guanidine hydrochloride are described. Treatment of the hydrochloride salt of 3 with nitric acid at low temperature generates the nitrate salt of 3 and not octahydro-2,5-bis(nitroimino)imidazo[4,5-d]imidazole (1a) as previously reported. The bis(nitroimino) compound (1a) was obtained by slow addition of nitric acid to a mixture of the monohydrochloride salt of the bicyclic guanidine (3) and acetic anhydride.
