  摘要：

  The reaction of tetrakis(chloromethyl)silane, Si(CH2Cl)(4), with sodium azide afforded tetrakis(azidomethyl)silane (sila-pentaerythrityl tetraazide, Si(CH2N3)(4) (1b)). Nitration of tetrakis(hydroxymethyl)silane, Si(CH2OH)(4), with nitric acid resulted in the formation of tetrakis(nitratomethyl)silane (sila-pentaerythritol tetranitrate, Si(CH2ONO2)(4) (2b)). Compounds 1b and 2b are extremely shock-sensitive materials and very difficult to handle. Spectroscopic data were obtained as good as sensitivity and safety allowed for umambiguous identification. Quantum chemical calculations (DFT) of the C/Si pairs C(CH2OH)(4)/Si(CH2OH)(4), 1a/1b, and 2a/2b regarding the structures and electronic populations were performed.

  Energetic Sila-Nitrocarbamates: Silicon Analogues of Neo-Pentane Derivatives

  摘要：

  Four silanes based on the neo-pentane skeleton Me4-xSi(CH2R)(x) containing carbamate groups (x = 14, R = OC(O)NH2) have been prepared via the corresponding alcohols Me4-xSi(CH2OH)(x), starting from the chlorosilanes Me4-xSiClx. Subsequent nitration leads to the corresponding primary nitrocarbamates (R = OC(O)NHNO2), examined for the purpose as potential energetic materials, including the silicon analogue of pentaerythritol tetranitrocarbamate (sila-PETNC) and a siloxane based nitrocarbamate side-product. All compounds were thoroughly characterized by spectroscopic methods including X-ray diffraction. Thermal stabilities and sensitivities toward impact and friction were examined, as well as detonation values by calculating energies of formation using the EXPLO5 V6.02 software.

  Me4−nSi[CH2Si(SiMe3)3]n [n = 1 (5), n = 2 (6), n = 3 (7)] and Me3−n(TMOP)Si[CH2Si(SiMe3)3]n [TMOP = 2,4,6-trimethoxyphenyl, n = 1 (9), n = 2 (10)] was synthesized by treatment of the corresponding (chloromethyl)silanes with [tris(trimethylsilyl)silyl]potassium−18-crown-6 (12). Reaction of tetrakis(chloromethyl)silane (4) with 12, however, yielded the unexpected disilacyclobutane derivative 1,1-bis(trimethylsilyl)-3
