Synthesis of cooligomers of titanium-bridged silsesquioxanes and octakis(hydridosilsesquioxane)
New titanium-bridged silsesquioxanes having olefinic groups, Ti[(C-C5H9)(7)Si7O12(SiMe2R)](2) (R = vinyl, allyl), react with octakis(hydridosilsesquioxane) under hydrosilylation reaction conditions to give oligomeric materials. The local structure around the titanium atoms of the starting silsesquioxanes is unchanged even in the oligomeric materials.
