Thiolate-Protected Aun Nanoclusters as Catalysts for Selective Oxidation and Hydrogenation Processes

Thiolate-protected Aun clusters are exploited as homogeneous and supported catalysts for two chemical processes: i) the selective oxidation of styrene by O2 to benzaldehyde and ii) the chemoselective hydrogenation of α,β-unsaturated ketone to α,β-unsaturated alcohol. The results demonstrate that a quantum-size effect in Aun clusters plays a critical role in their catalysis. This work highlights the importance of pursuing quantum-sized gold clusters for catalysis.
