catalysts in the Mukaiyama aldol reaction. Reaction of three different PHOX ligands with [Fe(η5-Ind)I(CO)2] afforded the iodide salts of three complexes of the general formula [Fe(η5-Ind)(CO)(PHOX)]+ in 73–81% isolated yields. The molecularstructure of one of the new complexes was determined, revealing a pseudo octahedral coordinationgeometry about the iron center. The iron complexes are catalytically

ratios of the products was investigated. New iron(II) and iron(III) complexes bearing bis(imino)pyridine ligands were synthesized and successfully applied to the Mukaiyama aldol reaction. The two complexes [FeCl2 L] (L = bis(imino)pyridine ligand, 55% isolated yield) and [LFe(μCl)3FeCl3] (76%) were obtained employing FeCl2 and FeCl3 iron sources, respectively, and characterized by elemental analyses, mass
