Abstract

Les produits de la réaction entre un sel d'iridium (III) ou un hydrate de ce sel, une diphosphine contenant des groupes phosphine secondaires et un chlorure, bromure ou iodure d'ammonium ou métallique sont d'excellents catalyseurs d'hydrogénation pour la cétimine. L'utilisation de diphosphines chirales et de cétimines prochirales permet d'obtenir des amines secondaires diastéréoisomères avec des rendements élevés en matières optiques.
