O₂ Activation and Selective Phenolate ortho Hydroxylation by an Unsymmetric Dicopper μ‐η¹:η¹‐Peroxido Complex

Unusual reactivity: A novel unsymmetric dicopper complex gives rise to the unsymmetric species 1-O2 having a μ-η1:η1-O2 binding mode and reactivity patterns not previously observed for symmetric analogues. It is unreactive in oxygen atom transfer reactions, but it can selectively bind phenolate and mediate its ortho hydroxylation, thereby demonstrating a conceptually different tyrosinase model with exquisite selectivity.
