| 摘 要： | 研究了以SiO2为原料低温合成高反应活性的五配位硅酸酯, 并与1-氧代-1-磷杂-2,6,7-三氧杂双环2.2.2]-4-氯甲基辛烷反应合成出具有对称结构的双环笼状四配位硅, 通过红外光谱、13C和29Si固体核磁共振、质谱等测试手段确定了其结构. 热分析结果表明, 双环笼状四配位硅在700 ℃的失重仅为19.98%, 且炭层呈密实片层状, 说明目标产物具有优异的热稳定性和成炭性质.

| Abstract: | A novel caged bicyclic phosphorous quadridentate silicon complex was synthesized by reaction of 1-oxo-1-phospha-4-chloromethyl-2,6,7-trioxabicyclo2.2.2]octane with the pentacoordinate silicon com- plex, which was synthesized directly from SiO2 by non-carbothermal reduction. Structure of the synthesized substance was confirmed by FTIR, MS, 13C and 29Si MAS NMR spectra, while thermal analysis tests indi- cated that the target compound possessed exceptional thermal stability. |
