| titleOfInvention | Bidentate c,p chiral phosphine ligands |
| abstract | The invention is concerned with new phosphine ligands of formula I wherein R 1 and R2 are independently of each other alkyl, aryl, cycloalkyl or heteroaryl , said alkyl, aryl, cycloalkyl or heteroaryl may be substituted by alkyl, alkoxy, halogen, hydroxy, amino, mono- or dialkylamino, aryl, -S02-R7, - S03.macr. , -CO-NR8BR8", carboxy, alkoxycarbonyl, trialkylsilyl, diarylalkylsilyl, dialkylarylsilyl or triarylsilyl; R3 is alkyl, cycloalkyl, aryl or heteroaryl; R4' and R4 signify independently of each other hydrogen, alkyl or optionally substituted aryl; or R4'~ and R4 together with the C-ato m they are attached to form a 3-8-membered carbocyclic ring; dotted line is absent or is present and forms a double bond; R5 and R6 are independently of each other hydrogen, alkyl or aryl, R7 is alkyl or aryl; and R8 and R8' are independently of each other hydrogen, alkyl or aryl; the substituents attach ed by the bold bondsare in cis relation to each other; metal complexes with suc h ligands as well as the use of such metal complexes as catalysts in asymmetri c reactions. |
