Abstract

The polyamine dendrimer-encapsulated Cu complexes are capable of regioselectively catalyzing the oxidative coupling reaction of 2,6-dimethylphenol to tetramethyldiphenoquinone in high yield. The polyamine dendrimer nanovoids encapsulate Cu ions in such a manner that adjacent Cu centers are able to serve as active species for the reaction.
