The synthesis of a series of tridentate ligands based on a homochiral 1,2-diamine structure attached to a triazole group and their subsequent applications to the asymmetric transfer hydrogenation of ketones are described. In the best cases, alcohols of up to 93% ee were obtained. Although base is not required, the use of Ru3(CO)12 as metal source is essential, indicating a unique mechanism for the
描述了基于与三唑基连接的同手性1,2-二胺结构的一系列三齿配体的合成及其在酮的不对称转移氢化中的后续应用。在最佳情况下,获得的酒精含量高达ee的93%。尽管不需要碱,但是必须使用Ru 3(CO)12作为金属源,这表明形成活性催化剂的独特机理。
