Two Exceptional Homoleptic Iron(IV) Tetraalkyl Complexes

Two Exceptional Homoleptic Iron(IV) Tetraalkyl Complexes

The formation of the high-valent iron complex [Fe(cyclohexyl)4] from FeII under reducing conditions is best explained by disproportionation of a transient organoiron intermediate which is driven by dispersive forces between the cyclohexyl ligands and the formation of short and strong Fe−C bonds. The (meta)stability of this diamagnetic complex (S=0) is striking if one considers that it has empty d-orbitals at its disposal and contains, at the same time, no less than twenty H-atoms available for either α- or β-hydride elimination. Let's hold together: The homoleptic and diamagnetic FeIV complex [Fe(cyclohexyl)4] is spontaneously formed under reductive conditions on treatment of FeX2 (X=Cl, acac) with excess C6H11MgCl. This unorthodox species is (meta)stable, even though the high-valent metal center has three empty d-orbitals at its disposal and is surrounded by no less than 20 hydrogen atoms available for α- or β-hydride elimination.
