  Isolation and characterization of an iron biliverdin-type complex that is formed along with verdohemochrome during the coupled oxidation of iron(II) octaethylporphyrin

  摘要：

  The coupled oxidation process, which is a model for oxidative heme degradation, has been shown to produce not only verdoheme, which was first described in 1930, but also a paramagnetic iron complex. Treatment of (OEP)-Fe(II)(py)2 (OEP is the dianion of octaethylporphyrin) with air and ascorbic acid in pyridine (py) solution yields 50% diamagnetic [(octaethyloxaporphyrin)Fe(II)(py)2]Cl, a verdoheme, and 32% paramagnetic {(OEB)Fe(III)2 (OEB is the octaethylbilindione trianion, a biliverdin analog). Dimeric {(OEB)Fe(III))2 has been identified by a combination of H-1 NMR and X-ray crystallographic studies. In this dimer, each iron is coordinated to four nitrogen atoms from one OEB trianion and an oxygen from another OEB ligand. Treatment of {(OEB)Fe(III))2 with hydrochloric acid gives blue octaethylbilindione in 91% yield. In pyridine-d5 solution, H-1 NMR studies show that {(OEB)Fe(III)}2 undergoes cleavage of the Fe-O bond to form (OEB)Fe(III)(py)2. This process is reversible.

  zinc amalgam produces the known iron(III) complex of biliverdin, FeIII(OEB)}2. The unusual pattern of resonances in the 1H NMR spectrum of 2 and its facile reduction to FeIII(OEB)}2 indicate that 2 is an oxidized complex that can be formulated by resonance structures involving either an Fe(IV) ion bound to a bilindione trianion or an Fe(III) ion bound to an oxidized, dianionic, radical form of the
