The Lanthanides are typically known for their preference to exist as +3 ions, which precludes them from performing chemical transformations that require redox processes. However, redox active ligands are capable of facilitating redox chemistry at metals that would not otherwise be able to participate in these important reactions. Our group has successfully demonstrated such ligands can mediate redox processes at uranium, imparting transition-metal like reactivity. Recently, we have adapted this strategy to the Lanthanides, showing that performing redox chemistry at the ligand frameworks can serve as a general strategy to perform multi-electron redox reactions.  Our most recent studies involving neodymium will be presented, including the synthesis and characterization of new species bearing redox active ligands, as well as their reactivity towards a variety of substrates.  Full spectroscopic and structural characterization will also be discussed.
