Iron catalyzed hydrogenation and electrochemical reduction of CO2: The role of functional ligands

Publication date: Available online 22 February 2018 Source:Journal of Organometallic Chemistry Author(s): Arne Glüer, Sven Schneider The reduction of CO2 is an attractive route to utilize the green-house gas as a C1 building block. In recent years, the scientific progress that could be obtained for CO2 hydrogenation to formate and electrochemical reduction mainly to CO was strongly driven by the development of molecular iron catalysts with high activities and selectivities. However, these advances are also associated with the utilization of functional ligands that facilitate, e.g. H2 heterolysis in thermal hydrogenation or the storage of redox-equivalents in electrochemical transformations. In this review the use of such cooperating and redox non-innocent ligands in iron catalyzed CO2 transformations is discussed with the aim at providing some guidelines for catalyst design and improvement.
