ABSTRACT:
The invention relates to compounds of formula (I) provided in the form of racemic compounds, mixtures of diastereomers or essentially pure diastereomers, wherein R1represents a hydrogen atom or C1-C4-alkyl, and at least one secondary phosphine depicts an unsubstituted or substituted cyclic phosphine group, or phosphonium salts thereof having one or two monovalent anions or a divalent anion. The compounds of formula (I) can be obtained by means of a novel method and are valuable ligands for catalytically active metal complexes in asymmetrical synthesis
