Intramolecular Arene Hydroxylation versus Intermolecular Olefin Epoxidation by (μ-η<sup>2</sup>:η<sup>2</sup>-Peroxo)dicopper(II) Complex Supported by Dinucleating Ligand
A discrete (mu-eta2:eta2-peroxo)Cu(II)2 complex, [Cu2(O2)(H-L)]2+, is capable of performing not only intramolecular hydroxylation of a m-xylyl linker of a dinucleatingligand but also intermolecular epoxidation of styrene via electrophilic reaction to the C=C bond and hydroxylation of THF by H-atom abstraction.
