不对称催化氢化反应中立体选择性探讨——在均相不对称催化氢化反应中,催化剂的手性膦配体结构对立体选择性的影响

Discussion on stereoselectivity in asymmetric catalytic cydrogenation

讨论了与过渡金属组成配合物对特定反应具有专一催化作用的典型旋光性膦配体的结构 ,认为当催化剂配体为二元螯合膦、配体磷原子上有环状取代基等关系时 。

The structure of typical optical phosphine coordination,which can not only compose coordination compound with transitional metal,but also have catalytic function on definite reaction,is discussed.Higher stereoselectivity can be obtained when catalytic promoter is binary phosphine chelate or when there is annular substituting group on phosphorus of coordination.
