Reaction of a Biomimetic Molybdenum-Centered Complex with Carbon Dioxide.
The global warming scare has prompted scientists of all disciplines to look into effective ways of dealing with carbon dioxide. Carbon dioxide’s ubiquity and stability in our atmosphere makes the carbon dioxide problem particularly daunting. Many processes in nature, however, have already found ways to convert carbon dioxide into fuel precursors; for example, the enzyme formate dehydrogenase (FDH) can reversibly convert carbon dioxide into formate. Our hope is that by copying the reactive part (i.e. the active site) of FDH, we can induce a similar reaction with a chemical complex made in the lab. We synthesized and characterized the biomimetic complex MoO(C2S2Ph2)22-, then reacted it with carbon dioxide. We aim to identify the product of the reaction using various spectral techniques (IR, UV-Vis, NMR, ESI, GC-MS, EPR) with hopes that the carbon dioxide molecule bind onto the metal center. Our findings give evidence for the formation of a molybdenum (V) dimer.
