Cooperative C-H Bond Activation by a Low-Spin d⁶ Iron-Aluminum Complex.

ABSTRACT: The reactions of transition metal complexes underpin numerous synthetic processes and catalytic transformations. Typically, this reactivity involves the participation of empty and filled molecular orbitals centered on the transition metal. Kinetically stabilized species, such as octahedral low-spin d⁶ transition metal complexes, are not expected to participate directly in these reactions. However, novel approaches that exploit metal-ligand cooperativity offer an opportunity to challenge these preconceptions. Here, we show that inclusion of an aluminum-based ligand into the coordination sphere of neutral low-spin d⁶ iron complex leads to unexpected reactivity. Complexes featuring an unsupported Fe-Al bond are capable of the intermolecular C-H bond activat
