Superparamagnetic core–shell radical polymer brush as efficient catalyst for oxidation of alcohols to aldehydes and ketones

Abstract

Nitroxide polymer brush grafted on superparamagnetic nanoparticles has been synthesized. Using the brush as a catalyst, the conversion by catalytic oxidation of alcohols to aldehydes and ketones is more than 99%. The catalyst can be easily recovered by applying a magnetic field. Furthermore, the reused catalyst still maintain high performance in catalytic oxidation.
