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.
