Wet oxygenase models: Unprecedented high levels of water incorporation into products (up to 75 %) is observed in epoxidation reactions with H2O2 by a bioinspired nonheme iron catalyst. A surprising substrate‐dependent incorporation of water is observed, and is proposed to arise from fast equilibrium between two high‐valent HOFeVO isomeric species exhibiting different reactivity ​
