Unusual reactivity: A novel unsymmetricdicoppercomplex 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 orthohydroxylation, thereby demonstrating a conceptually different tyrosinase model with
