Biomimetic Oxidation of Alcohols Catalyzed by TEMPO-Functionalized Polyethylene Glycol and Copper(I) Chloride in Compressed Carbon Dioxide

Abstract Recyclable TEMPO-functionalized polyethylene glycol [PEG 6000 -(TEMPO) 2 ] in combination with cuprous chloride were developed for biomimetic oxidation of a series of benzylic, allylic, heterocyclic alcohols, and 2-phenylethanol into the corresponding aldehydes or ketones in high selectivit...

Description
Summary:Abstract Recyclable TEMPO-functionalized polyethylene glycol [PEG 6000 -(TEMPO) 2 ] in combination with cuprous chloride were developed for biomimetic oxidation of a series of benzylic, allylic, heterocyclic alcohols, and 2-phenylethanol into the corresponding aldehydes or ketones in high selectivity and in moderate to high conversion in compressed CO 2 , which enhanced the catalytic activity as well as improved the selectivity.
