We report here functionalizing borasilsesquioxanes in a cross‐metathesis reaction in the presence of a ruthenium catalyst. The procedure provides new, silsesquioxanes containing boron atoms in their structure, which may find potential application in the preparation of special materials, e.g. flame retardants for polymers, organoboron Lewis acids for catalysts and scavengers, or molecular probes. The most attractive aspect of this study was obtaining hybrid silsesquioxane systems in the metathesis reaction of styrylborasilsesquioxane with mono‐ and octavinylsilsesquioxanes as well as diborate systems with vinylborate derivatives. Most of the compounds were obtained in good yields (> 75 %) and were characterized by spectroscopic methods (NMR, MALDI‐TOF‐MS).

通过4-乙烯基苯基硼硅倍半硅氧烷的易位转化获得新的功能化硼硅倍半硅氧烷

我们在这里报告了在钌催化剂存在下，在交叉复分解反应中将硼硅倍半氧烷官能化的过程。该程序提供了结构中含有硼原子的新型倍半硅氧烷，可在制备特殊材料中找到潜在的应用，例如用于聚合物的阻燃剂，用于催化剂和清除剂的有机硼路易斯酸或分子探针。这项研究最吸引人的方面是在苯乙烯基硅倍半氧烷与单和八乙烯基硅倍半氧烷的复分解反应中获得杂化倍半硅氧烷系统，以及乙烯基硼酸酯衍生物的二硼酸酯系统。大多数化合物均以高收率（> 75％）获得，并通过光谱法（NMR，MALDI-TOF-MS）进行了表征。
