Magnetic core–shell Fe3O4@Cu2O and Fe3O4@Cu2O–Cu materials as catalysts for aerobic oxidation of benzylic alcohols assisted by TEMPO and N-methylimidazole

Abstract

Robust core–shell magnetic materials catalyse quantitatively the aerobic oxidation of a wide range of benzylic alcohols into corresponding aldehydes at room temperature showing excellent tolerance towards the substituents on the phenyl ring.
