Introduction of organogermyl functionalities to cage silsesquioxanes

摘要: In this work, we present the first example of highly efficient platinum-catalyzed hydrosilylation vinyl- and allylgermanes with different types silsesquioxanes spherosilicates. This protocol allows straightforward introduction organogermyl functionalities alkyl chains linked to silsesquioxane core good yields excellent selectivity. These derivatives may be applied as precursors for development advanced hybrid materials in future. addition, a comparison made between vinylsilanes vinylgermanes showed higher reactivity germanium compounds reaction. To best our knowledge, is literature functionalization spherosilicates these derivatives. The reaction parameters kinetics were determined by situ FT-IR. research supported extensive data obtained from NMR measurements.
