Abstract
Abstract Compounds of the formula (I) in the form of racemates, enantiomerically pure diastereomers or a mixture of diastereomers, where the radicals Rare identical or different and are each C-C-alkyl; m is 0 or an integer from 1 to 4; n is 0 or an integer from 1 to 3; p is 0 or an integer from 1 to 5; Ris an aromatic hydrocarbon radical or a C-bonded heterohydrocarbon radical and Ris an aliphatic or C-bonded heteroaliphatic hydrocarbon radical; Rand Rare identical or different and are each an aliphatic or C-bonded heteroaliphatic hydrocarbon radical; Ris an unsubstituted or C-C-alkyl-, C-C-alkoxy- or halogen-substituted hydrocarbon radical; and A is a secondary amino group, are ligands for metal complexes which are suitable as catalysts for homogeneous enantioselective hydrogenation.
