Alkenyl-Functionalized Open-Cage Silsesquioxanes (RSiMe₂O)₃R'₇Si₇O₉: A Novel Class of Building Nanoblocks.

ABSTRACT: Trifunctional incompletely condensed polyhedral oligomeric silsesquioxanes (RSiMe₂O)₃R'₇Si₇O₉ (IC-POSSs) are considered as intriguing building nanoblocks dedicated to constructing highly advanced organic-inorganic molecules and polymers. Up to now, they have been mainly obtained via hydrosilylation of olefins, while the hydrosilylation of the C≡C bonds has not been studied at all, despite the enormous potential of this approach resulting from the possibility of introducing 3, 6, or even more functional groups into the IC-POSS structure. Therefore, in this work, we present a highly selective and efficient synthesis of the first example of tripodal alkenyl-functionalized IC-POSSs, obtained via platinum-
