Abstract New well-defined Fe II complexes bearing bi-and tridentate α-aminopyridine ligands were synthesized, and their catalytic activity in the oxidation of hydrocarbons and alcohols utilizing peroxide oxidants was investigated. The tridendate bis (picolyl) amine ligand 6 and its benzylated analogue 7 were converted into complexes [Fe II (6) 2] OTf 2 (96%, X-ray; OTf= CF 3 SO 3−) and [Fe II (7) 2] OTf 2 (90%). The bidentate aminopyridine ...
