Nitroguanidine is an individual explosive with an established reputation. It is widely used as a component of gunpowder, rocket propellants, and high explosives. Less known and appreciated, however, is its importance as a substrate in the synthesis of other explosive compounds with even better properties. In this work available information on synthetic methods, structure, and properties of compounds containing the nitroguanidine moiety was collected and analyzed. The most attention was paid to compounds that have already found practical applications and those with unique properties (high-performance, lowsensitivity), as well as compounds that can be further functionalized with energetic functional groups. The results of our literature search indicate that the nitroguanidine moiety should be treated as a particularly interesting building block from the point of view of the synthesis of new highenergy compounds.

“…Researchers also demonstrated that the moisture stability of 1,2‐dinitroguanidine (DNG) and 1,1‐diamino‐2, 2‐dinitroethene (FOX‐7), were superior to that of 1,2‐dinitrourea (DNU) (Figure ). Then, it led to the idea of replacing the oxygen atoms from the carbonyl position by other energetic functional atoms or groups to improve the stability.…”

A family of high energy density materials based on "565" chemical structure were designed and the spatial structure, heat of formation, detonation velocity, detonation pressure and sensitivity of each compound were investigated systematically by density functional theory. The results show that all the designed molecules possess high positive heat of formation (from 336.8 to 4135.7 kJ mol À1 ) and moderate detonation properties (detonation velocities range from 6.15 to 11.69 km s À1 and detonation pressures range from 16.4 to 68.28 GPa). Based on the values of detonation properties, impact sensitiv-ities (range from 6.8 to 54.3 cm) and bond dissociation energies (range from 30.7 to 402.6 kJ mol À1 ), compounds A1, A2, A4 and B4 were selected as the potential high energy density materials. Then frontier molecular orbital, electrostatic potential on the surface and thermal dynamic parameters of these selected molecules were simulated to give a better understanding of their chemical and physical properties. Also, a reasonable synthetic path of the selected molecules were provided for further experimental synthesis and testing.

“…Not surprisingly, 1,1-diaminoethene and guanidine ( Figure 2) consist of this type of structure with high nitrogen content of 48.23% and 71.14% respectively, and exist a large amount of C-N or N-N chemical bonds. To our knowledge, 1,1-diaminoethene and guanidine as energetic materials were mainly expressed in the following form: 1,1-diamino-2,2-dinitroethene, 8,9 1,2,3-triaminoguanidine, 10 1,2-dinitroguanidine, 11 energetic salts [12][13][14][15][16][17] and 1,1-diamino-2,2dinitroethene or guanidine based individual explosives ( Figure 2). 18,19 Although there are many species of 1,1-diaminoethene or guanidine based energetic materials, each has different advantages and disadvantages with respect to the stabilities and deto nation properties.…”

A series of cyclic energetic derivatives based on nitroguanidine and 1,1-diamino-2,2-dinitroethene were theoretically designed. The spatial structures, infrared spectrometry, heats of formation, electronic structures, detonation properties, and thermal stabilities of these designed compounds were fully investigated by density functional theory. It is found that all the designed compounds have moderate stabilities (bond dissociation energies range from 11.3 to 99.0 kJ mol-1), high crystal densities (from 1.9589 to 2.00188 g cm-3), high positive heats of formation (from 649.6 to 1060.8 kJ mol-1) and high positive heats of detonation (from 1074.77 to 1332.06 cal g-1) which lead to the excellent detonation properties (detonation velocities range from 8.71 to 9.05 km s-1 while detonation pressures range from 35.47 to 38.55 GPa). Electronic structures such as electrostatic potentials on the surface, electronic densities, highest occupied molecular orbitals, lowest unoccupied molecular orbitals and their energy gaps were also simulated to give a better understanding of chemical and physical properties of these compounds. All the data may shine lights on the explosive searching and synthesis.
