<b>Organic-inorganic hybrid materials. I: Synthesis, characterization and thermal properties of a novel polyhedral cubic silsesquioxane</b>

Abstract

Hydrosilylation of 2-chloroethylvinyl ether by octahydridosilsesilsesquioxane catalyzed by hexachloroplatinic acid gives a quantitative yield of 3 as white crystals. Thermogravimetric analysis of Si₈O₁₂(CH₂CH₂OCH₂CH₂Cl)₈ 3 revealed that it is thermally reasonably stable. Spectroscopic data and a crystal structure determination have been used to confirm the integrity, structural and molecular connectivity of the novel compound.
