Frontispiece: Exceptional Substrate Diversity in Oxygenation Reactions Catalyzed by a Bis(μ‐oxo) Copper Complex

The tyrosinase‐like activity of a new bioinspired bis(μ‐oxo) dicopper(III) catalyst was investigated herein. The hybrid guanidine‐stabilized catalyst revealed a remarkable oxygenation activity on diverse phenolic substrate classes, products of which were consistently predicted by DFT calculations. The selective C−H activation of mono‐ and bicyclic substrates provides a new benchmark to future developments on tyrosinase model systems on the route to atom‐economic oxygen‐transfer reactions.
