What is Mechanistic Tuning of Hydrocarbon Oxidations with H~2~O~2~, Catalyzed by Hexacoordinate Ferrous Complexes about?

## Abstract A comparison of the catalytic properties of a series of Fe^II^LXY complexes on oxidation reactions with H~2~O~2~, [L = __N__,__N__′‐bis(pyridin‐2‐yl‐methyl)‐__N__,__N__′‐bis(3,4,5‐trimethoxybenzyl)ethane‐1,2‐diamine] indicates that the lability of the X and Y ligands (Cl^−^ or CH~3~CN) determines the nature of the oxidation pathway. The absence of a labile site in the complex, i.e. when X = Y = Cl^−^, causes the reaction to proceed via a Fenton pathway (generation of hydroxyl radicals, exclusively). The presence of two labile CH~3~CN ligands (X = Y = CH~3~CN) allows the catalysis to proceed through a metal‐based mechanism, whereas in the case of a complex with only one labile ligand (X = Cl^−^ and Y = CH~3~CN), the reaction is less controlled by the metal. We wish to emphasize that the cleavage of the O−O bond in the Fe−OOH moeity, a key intermediate in the reaction, is different in the last two cases. (© Wiley‐VCH Verlag GmbH & Co.
