My comment: Not feasible for large scale? Abstract
The activation of carbon dioxide by transition metals is widely recognized as a key step for utilizing this greenhouse gas as a renewable feedstock for the sustainable production of fine chemi-cals. However, the dynamics of CO2-binding and unbinding to and from the ligand sphere of a metal have never been observed in the time domain. Here, we use the ferrioxalate anion in aqueous solution as a unique model system for these dynamics and apply femtosecond UV-pump mid-infrared-probe spectroscopy to explore its photo-induced primary processes in a time resolved fashion. Following optical excitation, a neutral CO2 molecule is expelled from the complex within ~500 fs to generate a highly intriguing penta-coordinated ferrous dioxalate that carries a bent carbon dioxide radical anion ligand, i.e. the reductively activated form of CO2, which is "end-on"-coordinated to the metal center via one of its two oxygen atoms.
