Inside Cover: Aerobic Oxidation of Alcohols at Room Temperature and Atmospheric Conditions Catalyzed by Reusable Gold Nanoclusters Stabilized by the Benzene Rings of Polystyrene Derivatives (Angew. Chem. Int. Ed. 22/2007)
Polymer-incarcerated gold nanoclusters catalyze the aerobic oxidation of various alcohols to aldehydes and ketones under ambient conditions. As described by S. Kobayashi and co-workers in their Communication on page 4151 ff., the nanoclusters were prepared by microencapsulation of gold in a copolymer based on polystyrene followed by cross-linking. The oxidation reactions catalyzed by the nanoclusters proceed without heating, with only molecular oxygen consumed and water generated as the sole side product.
