An aminated series: A well‐defined iron‐catalyzed reductive amination reaction of aldehydes and ketones with aliphatic amines using molecular hydrogen is presented. Under mild conditions, good yields for a broad range of alkyl ketones as well as aldehydes were achieved.

frustrated Lewis pair” approach, a cyclopentadienone iron tricarbonyl complex has been designed and applied in the reductiveamination and hydrogenation of bicarbonate. This well‐defined phosphine‐free complex displays the best activities reported to date for an ironcomplex in the reduction of bicarbonate into formate and in reductiveamination.
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
