Aerobic Oxidation of Hydroquinone Derivatives Catalyzed by Polymer-Incarcerated Platinum Catalyst

It's a lock‐in! A remarkably wide substrate scope of hydroquinones are oxidized to quinones in high yields in a platinum‐catalyzed process with as low as 0.05 mol % catalyst. The aerobic oxidation is catalyzed by platinum nanoclusters trapped in a styrene‐based polymer network (see scheme, PI P...

Description
Summary:It's a lock‐in! A remarkably wide substrate scope of hydroquinones are oxidized to quinones in high yields in a platinum‐catalyzed process with as low as 0.05 mol % catalyst. The aerobic oxidation is catalyzed by platinum nanoclusters trapped in a styrene‐based polymer network (see scheme, PI Pt=polymer‐incarcerated nanoclusters). The catalyst could be reused at least 13 times without any loss of catalytic activity.
