Abstract

Catalytically active copper bis(pyrazolyl)methane complexes have been anchored into pVCL-GMA microgels on specified positions within the microgel network. Functionalized microgels act as nanoreactors providing a tailored environment and stabilization for the copper complexes thus increasing the product yield. The oxidation of benzyl alcohols to their respective aldehydes was chosen as a test reaction to show the enhancement of catalytic activity due to the immobilization of the copper complex compared to the copper salt and the molecular copper complex.
