Abstract
A catalyst for hydrosilylation is provided. The catalyst comprises a nanoparticle having a surface and a plurality of ligands are tethered to the surface of the nanoparticle. Each ligand includes an independently selected cyclic aliphatic hydrocarbon group having one unsaturated moiety. Platinum is bonded to the unsaturated moiety the cyclic aliphatic hydrocarbon group in the catalyst. A method of preparing the catalyst is also provided. The method comprises mixing a ligand functionalized nanoparticle and a platinum mixture to give the catalyst.
Claims15
A catalyst for hydrosilylation, said catalyst comprising:
- a nanoparticle having a surface;
- a plurality of ligands tethered to the surface of the nanoparticle, each ligand independently having the following formula:
- wherein each X is an independently selected cyclic aliphatic hydrocarbon group having one unsaturated moiety, each D is a divalent group, and each R1 is independently selected from H, an alkyl group having from 1 to 8 carbon atoms, and a covalent bond to the surface of the nanoparticle;
- and
- platinum bonded to the unsaturated moiety of X.
