Abstract

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.
