B3LYP/cc‐pVDZ, B3LYP/3‐21G, MP2/6‐31G*, and MP2/3‐21G levels of theory are used to explain the chemical and physical behavior of the compounds with X=Cl, Br, I, N3, and ONO2. A new decomposition pathway of hexakis(nitratomethyl)disiloxane is presented and is used to explain their remarkable instability. The energetic properties and values of the nitrate and azide derivatives were calculated at the CBS‐4M level
取代六甲基二硅氧烷((XCH 2)3 Si)2 O的结构和化学性质的研究;报告了X = F,Cl,Br,I,N 3和ONO 2。提出了制备前体六(氯甲基)二硅氧烷的新合成途径。X = Cl,Br,I和N 3的产物通过NMR,IR和拉曼光谱法表征。此外,还详细讨论了X = Cl,Br和I的产物的单晶结构。X = F和ONO 2的化合物并非以其纯净形式获得;相反,对分解产物的研究表明它们已转化为中间体。B3LYP / cc-pVDZ,B3LYP / 3-21G,MP2 / 6-31G *和MP2 / 3-21G气相结构的理论计算用于解释化合物的化学和物理行为X = Cl,Br,I,N 3和ONO 2。提出了六(硝基甲基)二硅氧烷的新分解途径,并用于解释其显着的不稳定性。通过使用改进的EXPLO5计算机代码版本6.01,在CBS-4M的理论水平上计算了硝酸盐和叠氮化物衍生物的能量性质和值。
