Abstract

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.
