Estimating the term…
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.
