In 2008 Bocarsly reported a stunning result: pyridinium cation acts as an extremely efficient catalyst for the electrochemical reduction of CO2 directly to methanol. It is assumed that the electrocatalytic mechanism requires the presence of both low lying π* energy levels in an aromatic amine, and a nitrogen pKa that allows for a Lewis acid-base interaction between the amine and CO2. Subsequent results strongly suggest that steric interference with the interaction between CO2 and the pyridyl-nitrogen may be an important factor that can modulate the catalytic reaction. In this poster, we will describe the synthesis of three sets of naphthyridine derivatives which present varying degrees of potential steric interference about the pyridyl nitrogen, thus offering the opportunity to probe the importance of steric effects on this potentially very important electrocatalytic mechanism. The relative catalytic activity of these naphthyridine derivatives for reduction of CO2 will be measured collaboratively with the Bocarsly lab.
