Recently, there has been an increased interest in napthyridines as ligands in the synthesis of transition metal complexes. Additionally, a renewed search for new CO2 reduction catalysts has been stimulated by the twin challenges for the coming century of: 1) lowering the atmospheric CO2 concentration, while 2) providing for the continued increase in demand for energy. Dipyridyl-transition metal complexes have been shown to be electrocatalysts and photocatalysts for such reactions. Although napthyridine-transition metal complexes show analogous photophysical and electrochemical properties to those of dipyridyl complexes, very little work has been done concerning the effectiveness of complexes of napthyridine as catalysts in the electrochemical and/or photochemical reduction of CO2. Our work has focused on synthesizing napthyridines and related metal complexes that can be tested as catalysts for single or multi-electron reductions of CO2. We will present the synthesis and crystal structures of three vital napthyridine complex precursors.
