A process is described for preparing aromatic and heteroaromatic amines of the general formula (I) Ar&#x2014;NRR, in which an aromatic compound with the general formula (II) Ar&#x2014;X is reacted in the presence of a catalyst with an amine of the general formula (III) H&#x2014;NRRand a base, wherein the catalyst is selected from transition metal complexes having one or more ligands with the general formula (IV).

Process for preparing aromatic and heteroaromatic amines

The invention relates to certain chiral transition metal catalysts, to the metal of which at least two structurally different monophosphorus ligands are bonded, at least one of said monophosphorus ligands being chiral. Said chiral transition metal catalysts are suitable as catalysts for use in asymmetric transition metal-catalyzed reactions, providing better enantioselectivities than in cases where only one structurally defined ligand is used.

Mixtures of chiral monophosphorus compounds used as ligand systems for asymmetric transition metal catalysis

Certain chiral monophosphites and their monothio derivatives are suitable as ligands in the asymmetrical transition-metal-catalyzed hydrogenation, hydroborination and hydrocyanation of prochiral olefins, ketones and imines.
