A new concept for catalytic reactions in aqueous media is demonstrated by using a temperature‐responsive polymer support, poly( N‐ alkylacrylamide), which is converted into a catalyst by assembly with phosphotungstic acid. At high temperature, the catalyst is highly active in the oxidation of alcohols with H 2 O 2 owing to the formation of emulsions, whereas the product and catalyst are easily separated at low temperature (see scheme).
