摘要
Activation of dioxygen on dicopper(I) centres was systematically investigated using a group of open-chain and a macrocyclic m-xylyl-based dinucleating ligand from a bioinorganic viewpoint. Even though intermediate peroxo-dicopper(II) species was not detected (even at -80°C for the open-chain system), the putative intermediate reacted with C-H groups in ligands giving oxygenated products (C-OH groups). Absorption, spectroscopic and magnetic properties of the final dicopper(II) complexes have been investigated.
