2) H_2-hydrogenation
氢气氢化
1.
Asymmetric hydrogenation of ketone is one of the most important and widely used synthetic methods to produce chiral alcohols in both organic synthesis and chemical industry In 1990s,Noyori and co-workers developedη~6-arene Ru(Ⅱ) complex withβ-diamines ligand which is efficient in transfer hydrogenation of ketones instead of H_2-hydrogenation of ketones in neutral and basic conditions.
该催化剂在碱性条件下主要发生转移氢化反应,很难发生氢气氢化反应。
