Sulfide Oxidation by O₂: Synthesis, Structure and Reactivity of Novel Sulfide-Incorporated Fe(II) Bis(imino)pyridine Complexes.

ABSTRACT: The unsymmetrical iron(II) bis(imino)pyridine complexes [Fe^II(LN₃SMe)(H₂O)₃](OTf)₂ (1), and [Fe^II(LN₃SMe)Cl₂] (2) were synthesized and their reactivity with O2 was examined. Complexes 1 and 2 were characterized by single crystal X-ray crystallography, LDI-MS, ¹H-NMR and elemental analysis. The LN₃SMe ligand was designed to incorporate a single sulfide donor and relies on the bis(imino)pyridine scaffold. This scaffold was selected for its ease of synthesis and its well-precedented ability to stabilize Fe(II) ions. Complexes 1 and 2 ware prepared via a metal-assisted template reaction from the unsymmetrical pyridyl ketone precursor 2-(O=CMe)-
