Disclosed are compounds of formulas (I) and (II) in the form of enantiomer-pure diastereomers o diastereomer mixtures. In said formulas (I) and (II), R'<SUB>1</SUB> represents C<SUB>1</SUB>-C<SUB>4</SUB> alkyl while n represents 0 or an integer from 1 to 5; R<SUB>1</SUB> represents a hydrogen atom, a hydrocarbon radical with 1 to 20 C atoms, secondary phosphino, a mercaptan radical with 1 to 20 C atoms in the hydrocarbon radical, or a silyl radical with 3 C<SUB>1</SUB>-C<SUB>12</SUB> hydrocarbon radicals; R<SUB>2</SUB> is the monovalent radical of an electrophilic organic compound; X<SUB>1</SUB> represents F, Cl, Br, or I; and Y represents vinyl, methyl, ethyl, -CH<SUB>2</SUB>-N(C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl)<SUB>2</SUB>, -CH<SUB>2</SUB>-OR wherein R is a hydrocarbon radical, or a C-bonded, S-bonded, or P-bonded chiral group that directs metals of metallization reagents into the ortho position X<SUB>1</SUB>. The inventive compounds are coordinating ligands for metal complexes of transition metals as homogeneous catalysts for coupling reactions and intermediate products for producing bidentate ligands. |
