Effect of iron and hemoproteins on hydrogen peroxide-supported styrene oxidation to styrene oxide

Summary Fe²⁺, Fe³⁺ and their complexes with EDTA and hemin, methemalbumin and methemoglobin were active catalyzers of H₂O₂ supported styrene oxidation to styrene oxide. Methemoglobin was the most active compound; its peroxidative activity was comparable to that of cytochrome P-450 in liver microsomes of phenobarbital-treated rats. Cumene hydroperoxide supported styrene oxidation with methemoglobin and microsomal hemoproteins and was found to be more efficient than H₂O₂.This work was supported by C.N.R.
