文摘

Diiron(II) complexes, [Fe₂(L^Ph4)(RCO₂)]²⁺ (R = Ph₃C or Ph), react with dioxygen to generate peroxodiiron(III) complexes [Fe₂(L^Ph4)(RCO₂)(O₂)]²⁺. Their reactivities can be greatly controlled by the stereochemistry of the bridging carboxylates. Thermal decomposition of a peroxo complex with Ph₃CCO₂ resulted in regioselective hydroxylation of one of phenyl groups of the supporting ligand, which mimics toluene monooxygenase hydroxylase activity, whereas a peroxo complex with PhCO₂ exhibited reversible deoxygenation.
