Abstract
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.
