Hydrosilylation reaction of allylacetate (AA) with octakis(dimethylsiloxy)octasilsesquioxane [(HSiMe2O)8(SiO1.5)8] was efficiently catalyzed by chloro(1,5-cyclooctadiene)iridium(I) dimer [Ir(μ-Cl)(COD)]2. The effects of the catalyst amounts and the reaction conditions on the conversion and the product selectivity were investigated. [Ir(μ-Cl)(COD)]2 catalyst was also applied to the hydrosilylation
Octakis(3-chloropropyl)octasilsesquioxane, obtained recently by a new method, has enabled a highly efficient synthesis of a whole family of cube-like T8 silsesquioxanes by nucleophilic substitution of chlorine atom with appropriate nucleophilic agents. Five functionalized silsesquioxanes, i.e., octakis[3-(methacryloyloxy)propyl]-, octakis(3-acetoxypropyl)-, octakis[3-(phenylamino)propyl]-, and oc
