Synthesis of a New Ligand Tris (2-pyridylmethyl) amine functionalized by a methoxy group and study of Dichloroferrous complexes, its reactivity to dioxygen both in the presence and absence of substrate

The biomimetic oxidations at active sites of iron proteins involve peroxides, especially hydrogen peroxide which is a strong and very convenient reagent since it is inexpensive and does not release any toxic by-products. In many cases however, Mother Nature uses molecular dioxygen to carry out major oxidation reactions in particularly attractive conditions. The biomimetic interest of iron complexes in the tris (2-pyridylmethyl) amine series (TPA) is no longer to demonstrate. Various α-substituted TPA-based ligands were prepared with the idea to modulate the electronic properties at the metal centre. A new type of ligand MeOTPA was prepared and the effect of (MeO) in the oxygenation of complex was studied
