An organosilicon compound can be efficiently produced by using metallic element-containing nanoparticles such as a platinum element-containing nanoparticle having a solvent on surface as a catalyst of the hydrosilylation reaction of alkenes.
Highly efficient and general Ir-catalyzed hydrosilylation of unactivated alkenes with excellent anti-Markovnikov regioselectivity was described. A broad scope of hydrosilylated products were synthesized economically and conveniently from commercially or naturally available compounds, which provides versatile valuable precursors for organic and medicinal studies.

Combined with Pt Nanoparticles: Characterization and Catalysis in Alkene Hydrosilylation
disclose a combination of N,N-dimethylformamide (DMF)-protected Fe2O3 nanoparticles (NPs) and Pt NPs catalyst system for the hydrosilylation of various functional alkenes and tertiarysilanes. The catalyst of DMF-protected Fe2O3/Pt NPs can be recycled for five times by a simple extraction. The developed combination Fe2O3/Pt NPs catalyst is effective up to the 1-kilogram scale.
