The present invention relates to catalytic materials for hydrogenation or asymmetric hydrogenation. In particular, the invention relates to iron (II) complexes containing unsymmetrical tetradentate diphosphine (PNN'P) ligands with two different nitrogen donor groups useful for catalytic transfer hydrogenation or asymmetric transfer hydrogenation of ketones, aldehydes and imines.

Redesign and reduce: The graphic shows some Ru complexes of tridentate ligands that do not contain NH substituents but can catalyse ketone reduction with zero‐order dependence on ketone. In tridentate systems, a secondary amine, not a primary amine, promotes hydrogen activation. Leading on from these observations, the Ru complex of a phosphine‐amino‐alcohol shown above has been found to be a good hydrogenation
