The invention relates to a novel class of ruthenium complexes containing phosphine and hybrid amine ligands, their preparation and use as catalysts in the reduction of simple ketones to alcohols by molecular hydrogenation. The reactivity and enantioselectivity of such complexes in the asymmetric hydrogenation of simple ketones could be enchanced by the addition of some selective additives.
这项发明涉及一类新型的
钌配合物,其中包含膦和
混合胺配体,以及它们的制备和在分子氢化反应中作为催化剂将简单酮还原为醇的用途。这种配合物在对简单酮进行不对称氢化反应时的反应性和对映选择性可以通过添加一些选择性添加剂来增强。
