Reductive amination under hydrogen pressure is a valuable process in organic chemistry to access amine derivatives from aldehydes or ketones. Knölker’s complex has been shown to be an efficient iron catalyst in this reaction. To determine the influence of the substituents on the cyclopentadienone ancillary ligand, a series of modified Knölker’s complexes was synthesised and fully characterised. These
A highly selective earth-abundant photocalytic system, based on an in situ copper photosensitizer and an iron catalyst, was developed for the CO2-to-CO transformation.
