Abstract

Abstract : A catalytic vortex producing quinones was realized by a (μ‐η 2 :η 2 )‐peroxo dicopper(II) core resembling the active centre of tyrosinase. This biomimetic species is stabilised by a new bis(pyrazolyl)imidazolylmethane ligand. Kinetic experiments show that this peroxide species mediates phenole hydroxylation with almost biological speed. This enhancement was achieved by exchanging a pyridinyl donor against the imidazolyl donor. For more details, see the Full Paper by S. Herres‐Pawlis and co‐workers onpage 17639 ff.
