摘要：A bio-inspired heme complex involving both a proton donor and an axial imidazole ligand reduces the activation energy for the formation of a ferric hydroperoxo intermediate. A high-spin ferrous heme is shown to be capable of reducing its superoxy species to generate a ferric hydroperoxo intermediate for the first time.
