Title:
FERROCENE-DIPHOSPHINE LIGANDS
Document Type and Number:
WIPO Patent Application WO2007017522
Kind Code:
A9
Abstract:
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.
