Magnesium and aluminum are highly abundant in the earth's crust and so the synthesis and study of their complexes as catalysts for potentially large scale processes warrants investigation. To overcome some of the limitations associated with the study of redox inactive metal ions, we have been exploring the chemistry of these ions in combination with redox non-innocent ligands. In this presentation I will describe two electron reduced, substituted bis(imino)pyridine (I2P) ligands and the coordination complexes they form with Mg(II)and Al(III). This work includes complexes of the symmetric methyl substituted bis(imino)pyridine ligand, and complexes of a new asymmetric ligand based on the bis(imino)pyridine framework. The new modifications have been designed to increase the stability of main group metal complexes especially under the protic reaction conditions that are necessary for dehydrogenation catalysis. Some of the metal complexes that will be discussed include [(MeI2P2-)Mg(THF)]2[(�-MgCl2), (MeI2P2-)Mg(THF)2, and (I2P2-)Al(THF)Cl.
