The functionalization of mono- and octahydrospherosilicate with vinylboranes and allylboranes via hydrosilylation reaction in the presence of a Karstedt's platinum (0) catalyst is presented. This is the catalytic route to obtain a new class of silsesquioxanes containing boron atoms in their structure in high yields (>90%) and with satisfactory selectivity. The obtained compounds were fully characterized by spectroscopic (H, C, Si NMR) and spectrometric methods (MALDI-TOF-MS), as well as thermal analysis (TGA). The obtained compounds were subjected to thermal tests, characterizing the processes of melting, thermal evaporation, sublimation and thermal decomposition.
本文介绍了 Karstedt's 铂（0）催化剂存在下通过硅氢加成反应将单氢和八氢笼形倍半硅氧烷与乙烯基硼烷和烯丙基硼烷官能化。这是催化路线，可在高收率（>90%）和令人满意的选择性下获得含有硼原子的新型硅倍半氧烷。通过光谱（H、C、Si NMR）和光谱方法（MALDI-TOF-MS）以及热分析（TGA）对获得的化合物进行了充分的表征。对所得化合物进行了热测试，表征了熔融、热蒸发、升华和热分解过程。
