Article Synopsis
- Redox metalloenzymes perform selective oxidation reactions using O or HO, producing harmless by-products like water under mild conditions.
- The study details a new non-heme Fe complex with a pentaazadentate coordination sphere and a phenol group that influences O or HO activation.
- Findings indicate that the phenol group aids in the formation of FeO from FeO-OH by facilitating the heterolytic cleavage of the O-O bond.
In the context of bioinspired OAT catalysis, we developed a tetradentate dipyrrinpyridine ligand, a hybrid of hemic and non-hemic models. The catalytic activity of the iron(III) derivative was investigated in the presence of iodosylbenzene. Unexpectedly, MS, EPR, Mössbauer, UV-visible and FTIR spectroscopic signatures supported by DFT calculations provide convincing evidence for the involvement of a relevant Fe-O-N active intermediate.

In comparison with the hexadentate ligand N,N,N',N'-tetrakis(pyridin-2-ylmethyl)ethane-1,2-diamine (TPEN), N,N'-bis[1-(pyridin-2-yl)ethyl]-N,N'-bis(pyridin-2-ylmethyl)ethane-1,2-diamine ( L ) has a methyl group on two of the four picolyl positions. Fe complexation by L yields two diastereomeric complexes with very similar structures, which only differ in the axial/equatorial positions occupied by the methylated pyridyl groups.
