In this paper, a new type of borasilsesquioxanes was synthesized through a condensation process, and its reactivity in catalytic hydrosilylation reactions with silanes, siloxanes, and silsesquioxanes was investigated. The obtained compounds were mostly obtained in >90% yield. They were fully characterized using spectroscopic (H, C, Si NMR) and spectrometric (MALDI-TOF-MS) methods. The next stage of the research involved studying the thermogravimetric properties of the borasilsesquioxanes. By analyzing the different stages of decomposition using spectroscopic techniques (NMR, ATR-FTIR, Raman) and microscopic imaging, it was found that the structure of the borasilsesquioxanes changed during the pyrolysis process and polymer compounds were formed.
本文通过缩合反应合成了一种新型的硼硅倍半氧烷，并研究了其在硅烷、硅氧烷和倍半硅氧烷的催化氢化反应中的反应活性。所得化合物的产率大多在>90%以上。它们使用光谱（H、C、Si NMR）和光谱（MALDI-TOF-MS）方法进行了充分的表征。研究的下一阶段涉及研究硼硅倍半氧烷的热重性质。通过使用光谱技术（NMR、ATR-FTIR、拉曼）和微观成像分析分解的不同阶段，发现硼硅倍半氧烷的结构在热解过程中发生了变化，形成了聚合物化合物。
