| Abstract: | A series of iron(II)/(III) and cobalt(II)/(III) complexes with the tetradendate tripodal ligands (2-aminoethyl)bis(2-pyridylmethyl)amine (uns-penp), its methylated derivatives Me2-uns-penp and Me4-uns-penp as well as the amide ligand N-acetyl-N,N-bis[(2-pyridyl)methyl]ethylenediamine (acetyl-uns-penp) were synthesized and structurally characterized. They have been investigated in regard to their reactivity towards dioxygen and/or hydrogen peroxide. Complexes of this type seem to have a high potential to be useful in the activation of dioxygen for selective oxidation reactions of organic substrates. |
