Gold nanoparticles of ca. 3 nm with a narrow size distribution were prepared using block or star-shaped polymers of vinyl ethers with pendant oxyethlene chains as a template in water. The polymers were synthesized by living cationic polymerization in the presence of an added base. Auric ions, weakly interacted with the oxyethylene units, were reduced with sodium borohydride to yield polymer-stabilized gold nanoparticles. These particles were shown to catalyze aerobic oxidation of benzylic alcohol in water at room temperature. Moreover, the reuse of the catalysts was examined by utilizing thermosensitivity of the polymer chains.
