Abstract
Compounds of the formula (I), in which Ris C-Calkyl, C-Caryi or C-C, aralkyl, Ris an open-chain or cyclic secondary amino group, and R is a radical of the formula in whichis C-Calkyl or C-Calkoxy, and Ris H, C-Calkyl or C-Calkoxy, are ligands for metal complexes as homogeneous hydrogenation catalysts for prochiral organic compounds containing double bonds, by means of which a very high activity and productivity and also enantioselectivity can be achieved
