The present disclosure relates to biaryl diphosphine ligands of the formula (B), processes for the production of the ligands and the use of the ligands in metal catalysts for asymmetric synthesis. The disclosure also relates to intermediates used for the production of the biaryl diphosphine ligand. (Formula (B)) 

Biaryl diphosphine ligands, intermediates of the same and their use in asymmetric catalysis

The present disclosure relates to a method for preparing a metal catalyst comprising at least one ligand that is coordinated to the metal through at least one phosphorous (P) atom and at least one nitrogen (N) atom, the method comprising reacting a metal pre-cursor complex with an acid addition salt of an aminophosphine, diaminophosphine, aminodiphosphine or diaminodiphosphine, in the presence of a base.
