reacting potassium triiodopyrazolate or triiodoimidazolate with corresponding dichloro compounds. All compounds were fully characterized by 1H and 13C NMR spectroscopy, IR spectroscopy, and elemental analyses. The structure of compound 1 was further confirmed by single-crystal X-ray diffraction. All of the compounds exhibit good thermal stability with decomposition temperatures between 199 and 270 °C

1,3‐Dichloro‐2‐nitro‐2‐azapropane is an excellent precursor to dense energeticfunctionalized dipyrazolyl‐N‐nitromethanamines. This new family of energetic compounds was fully characterized by using 1H, 13C, and 15N NMR and IR spectroscopy, differential scanning calorimetry, elemental analysis, and impact sensitivity tests. Additionally, single‐crystal X‐ray structuring was done for 3 and 5⋅CH3CN,

corresponding nitramine. 3-Nitramino-4-nitrofurazan is a very promising explosive regarding detonation performance but it suffers from its hygroscopicity, low thermal stability, and high sensitivity to external stimuli. The introduction of other nitramine groups either by alkylation with 1-chloro-2-nitrazapropane or by combination of two 3-nitramino-4-nitrofurazans yielded the corresponding more stable
