Document Type and Number:
Japanese Patent JP2001512431
Kind Code:
A
Abstract:
A description is given of new chiral phosphine ligands containing amino acid groups and having the formula IwhereR1 is hydrogen, a C1-C7-alkyl radical, a C6-C10-aryl radical or a monovalent metal, preferably sodium or potassium,R2 is hydrogen or a C1-C7-alkyl radical,R3 is hydrogen or an -NR5R6 radical, where R5 and R6 are identical or different and are hydrogen or C1-C7-alkyl or C6-C10-aryl radicals,m is 0 or 1,with the exception of the compounds in which R5 and R6 are hydrogen and at the same time R2 is hydrogen, R4 is phenyl and R1 is methyl or benzyl and a process for their preparation.These phosphine ligands are suitable as constituents of metal complexes which can be used as catalysts for reactions to form C-C, C-H, C-N, C-Si or C=O bonds.
