The invention relates to a process for the manufacture of ligands capable of forming metal complexes and such complexes; novel ligands with new backbones, complexes thereof with transition metals, the use of complexes of said ligands with transition metals as catalysts, as well as novel intermediates for the manufacture of said ligands. The ligand complexes are useful in stereoselective synthesis, especially hydrogenation, of various organic molecules. Especially, the process according to the invention is directed to the synthesis of compounds of the formulae IA and IIA, wherein the substituents have the meanings given in the description, and to novel compounds of these formulae as ligands.
