Ligand-Based Reduction of CO2 and Release of CO on Iron(II)
A synthetic cycle for the CO2-to-CO conversion (with subsequent release of CO) based on iron(II), a redox-active pydridinediimine ligand (PDI), and an O-atom acceptor is reported. This conversion is a passive-type ligand-based reduction, where the electrons for the CO2 conversion are supplied by the reduced PDI ligand and the ferrous state of the iron is conserved.
