Abstract: | A model for the key intermediate in copper oxygenase reactions, the Cu(II )–OOH complex, was prepared with the novel tripodal pyridylamine ligand, bis(6-pivalamide-2-pyridylmethyl)(2-pyridylmethyl)amine. The HOO? moiety is stabilized by hydrogen bonding to two amine H atoms (see structure on the right). |
