湿加氧酶模型：前所未有的高水平的水纳入产品（高达75%），观察到在环氧化反应与H2 O2的生物启发nonheme铁催化剂。观察到了令人惊讶的底物依赖性水掺入，并提出这是由两种表现出不同反应性的高价HO-2FeV-2 O异构体之间的快速平衡引起的。
Wet oxygenase models: Unprecedented high levels of water incorporation into products (up to 75 %) is observed in epoxidation reactions with H2O2by 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 HOFeVO isomeric species exhibiting different reactivity.
