摘要： Compounds of the formula (I) and (Ia) in the form of racemates, mixtures of diastereomers or in essentially enantiomerically pure form, (I), (Ia), where R is hydrogen, C1-C8alkyl, C5-C12cycloakyl, phenyl or phenyl substituted by from 1 to 3 C1-C4alky or C1-C4alkoxy groups; n is 0 or an integer from 1 to 4 and R1 are identical or different subtitutuents selected from the group consisting of C1-C4alkyl, C1-C4fluoroalkyl and C1-C4alkoxy; X1 and X2 are each, indenpendently of one another, secondary phosphino; T is C6-C20arylene or C3-C16heteroarylene; and X2 is bound in the ortho position relative to the T-cyclopentadienyl bond. The compounds are ligands for complexes of metal selected from transition groups (I) and (VIII) of the Periodic Table of the Elements, and these metal complexes are valuable catalysts for the asymmetric addition of hydrogen, boron hydrides or silanes onto carbon-carbon or carbon-heteroatom multiple bonds in prochiral organic compounds or the asymmetric addition of carbon nucleophiles or amines onto allyl compounds.

摘要： Compounds of the formula (I) in the form of racemates, mixtures of stereoisomers or optically pure stereoisomers, formula (I), where X1 and X2 are each, independently of one another, a secondary phosphino group; R1 is a halogen atom or a substituent bound via a C atom, N atom, S atom, Si atom, a P(O) group or a P(S) group to the cyclopentadienyl ring; R2 is C1-C4-alkyl or phenyl; m is from 1 to 3 and n is 0 or from 1 to 5, are ligands for complexes of transition metals as enantioselective and homogeneous catalysts. As a result of the substitution, the conversion, the stereoselectivity and/or the configuration of the adduct formed can be influenced and optimization of catalysts can be made possible in this way.
