Sequential Deoxygenation of CO and NO via Redox-Control of a Pyridinediimine Ligand with a Hemilabile Phosphine.

The deoxygenation of environmental pollutants CO and NO to form value-added products is reported. CO reduction with subsequent CO release and NO conversion to NO are achieved via the starting complex Fe(PDI)Cl (). contains the redox-active pyridinediimine (PDI) ligand with a hemilabile phosphine located in the secondary coordination sphere.
