Recently, our laboratory has been developing new strategies for the generation of catalytically active metal nanoparticles.1, 2, 3 We have been able to generate and stabilize a fair number of late transition metal nanoparticles via this strategy. In this presentation, we will present catalytic utility of nanoparticles to tailor olefins to silicon molecules via hydrosilylation reactions. We will demonstrate that a fair number of electronically and sterically varied olefins were quantitatively and regioselectively grafted to Si-H containing silicone molecules and oligomers. Furthermore, hybrid nanoarchitectures were generated by selective incorporation of olefin based polymers on predefined nanostructures, such as Octakis(dimethylsiloxy)-T8-silsesquioxane (Q8M8H) and 1,3,5,7 Tetramethylcyclo-tetrasiloxane (D4H).
