Provided is a process for preparing an optically active ruthenium-phosphine complex represented by the following formula (1):
1
wherein L represents a bidentate ligand compound of a tertiary phosphine; X represents a halogen atom; and * means chiral center (L* is an optically active substance), which comprises reacting a ruthenium-phosphine complex represented by:
Ru
m
X
n
L
p
A
q
or [RuX(D)(L)]X
wherein, X and L have the same meanings as described above (L is a racemic modification); A represents triethylamine (Et
3
N), etc.; and m, n, p and q each stands for an integer and D represents benzene, etc. with ½ equivalent of a specific optically active chiral diamine, thereby inactivating one of the enantiomers; and then with a specific optically active diamine derivative, thereby activating the other enantiomer.
提供了一种制备光学活性的
钌-膦配合物的方法,该配合物由以下公式(1)表示:1其中L代表三价膦的双齿
配体化合物;X代表卤素原子;*代表手性中心(L*是光学活性物质),包括将由以下表示的
钌-膦配合物反应而成:RumXnLpAq或[RuX(D)(L)]X其中,X和L具有如上所述的相同含义(L是外消旋修饰);A代表
三乙胺(Et3N)等;m、n、p和q各代表一个整数,D代表苯等。首先使用特定的光学活性手性二胺的½当量反应,因此使其中一个对映体失活;然后使用特定的光学活性二胺衍
生物,因此激活另一个对映体。
