Gold(0) nanoclusters, stabilized by poly(N-vinyl-2-pyrrolidone) (Au:PVP-n), catalyzed the oxidative homo-coupling reaction of potassium aryltrifluoroborate in water under air. Catalytic activity was dependent on the size of clusters. The smallest cluster Au:PVP-1 (dav = 1.3 ± 0.3 nm) gave the highest activity, while Au:PVP-7 (dav = 9.5 ± 1.0 nm) did not catalyze the homo-coupling. The catalyst was reusable for several times. Positively charged surface on the Au cluster, generated by the adsorption of molecular oxygen, would be the active site of the catalysis.
Gold(0) nanoclusters, stabilized by poly(N-vinyl-2-pyrrolidone) (Au:PVP-n), work as a selective, quantitative, and reusable catalyst for the homo-coupling reaction of potassium aryltrifluoroborates in neutral aqueous media under ambient condition.Figure optionsDownload as PowerPoint slide
