AMINO-PHOSPHINOALKYL-FERROCENES AND THEIR USE AS LIGANDS IN CATALYSTS FOR ASYMMETRIC REACTIONS

摘要

Compounds of the formulae (I) and (V) in the form of racemates, mixtures of stereoisomers or optically pure stereoisomers, where R is unsubstituted or F-, Cl-, OH-, C₁-C₄-alkyl- or C₁-C₄-alkoxy-subsituted C₁-C₈-alkyl, C₃-C₈-cycloalkyl-C₁-C₄-alkyl or C₇-C₁₁ i-aralkyl; X₁ is a secondary phosphino group; Ri is C₁-C₄-alkyl or phenyl; and n is 0 or from 1 to 5. The compounds are ligands for the formation of catalytically active metal complexes as asymmetric, homogeneous catalysts.
