Abstract

Mechanistic studies of H₂O₂ activation by complexes related to [(BPMEN)Fe^II(CH₃CN)₂]²⁺ with electron-rich pyridines revealed that a new intermediate formed in the presence of acetic acid with a 465 nm visible band can be associated with an unusual g = 2.7 EPR signal. We postulate that this chromophore is an acylperoxoiron(iii) intermediate.
