Description
Summary:Polystyrene-polyamidoamine-supported gold nanoparticles were prepared using a reductant-directed formation strategy. The resulting catalysts exhibited excellent activities in the aerobic oxidation of benzyl alcohols and the homocoupling of phenylboronic acids under mild conditions and can be recycled at least 14 times without significant loss of activity. Gold nanoparticles with excellent catalytic activities have been prepared by first complexation with a reductant on polystyrene-polyamidoamine beads and then reduction of a gold salt.
