Investigation of the alkylation ability of silylated nitroalcohols
摘要:
Beta-nitrosubstituted trimethylsilylated alcohols RCH2-O-SiMe3 [R = N(NO2)Me, C(NO2)Me2, C(NO2)2Me, C(NO2)3] have been studied. It has been shown that the trimethylsiloxy group is sufficiently reactive only in the N-nitro derivative in which it can be replaced by a chlorine atom or dimethylamino group upon the action of trimethylchlorosilane or pentamethyldisilazane, respectively.

New energy-rich derivatives of 2-nitroguanidine were obtained. The synthesis was based on the reaction of 1-chloromethyl-2-nitroguanidine, which was obtained by chlorination of 1-hydroxymethyl-2-nitroguanidine with sodium azide or salts of N-nitramines. The synthesized compounds can be of interest as potential components of both composite solid propellants and explosive compositions.

zolate with dimethyl sulfate was investigated yielding 1,4-dimethyl-5-nitriminotetrazole (16). All products (8–16) were determined by low temperature single X-ray diffraction. A comprehensive characterization and description of the chemical properties (IR, Raman, and multinuclear (1H, 13C and 15N) NMR spectroscopy, mass spectrometry, elemental analysis and differential scanning calorimetry) is given
comparative study details the syntheses and chemical characterisation of two newenergetic polynitromethyl tetrazole derivatives, namely, 2‐(2‐nitro‐2‐azapropyl)‐5‐(trinitromethyl)‐2 H‐tetrazole and its fluorine‐containing analogue 2‐(2‐nitro‐2‐azapropyl)‐5‐(fluorodinitromethyl)‐2 H‐tetrazole. Their crystal structures and energetic behaviour are compared to those of their starting materials, the ammonium
