Use of functionalized PEG with 4-aminobenzoic acid stabilized platinum nanoparticles as an efficient catalyst for the hydrosilylation of alkenes

A catalyst containing functionalized polyethylene glycol with 4-aminobenzoic acid (PEG-AMB) stabilized platinum nanoparticles has been synthesized and characterized, and its application in the hydrosilylation of alkenes investigated. It is shown that the functionalized PEG-stabilized Pt nanoparticles form a very efficient catalyst for the hydrosilylation of alkenes. The Pt nanoparticles can be fully immobilized in the PEG-AMB and recycled at least nine times without any obvious loss of catalytic activity.
