Abstract

original image

Away from the surface: Novel nanoparticles (NPs) consisting of 16 nm Au cores surrounded by Pd shells of various thicknesses catalyze Suzuki–Miyaura cross-coupling reactions in water at room temperature. NPs having shells of two to five Pd monolayers thick exhibit the highest catalytic activity. Catalysis was attributed to the leaching of Pd species from the NPs through the synergistic action of the carbonate base and the arylboronic acid.
