Abstract

A universal and green catalytic system for the hydrogenation of unsaturated aldehydes and ketones into the corresponding alcohols with the CC bonds retained under atmospheric hydrogen pressure in the water phase was realized by N-functionalized amino ligand-stabilized ruthenium complexes (o-PPh₂C₆H₄NHMe)[(CH₂NHR)₂]RuCl₂ (R = H, Me, Et) and (o-PPh₂C₆H₄NMe₂)[(CH₂NHEt)₂]RuCl₂ with wide substrate compatibility and excellent functionality tolerance. The structural synergism between o-PPh₂C₆H₄NHMe and (CH₂NHEt)₂ achieves the enhanced performance, with a positive correlation with the electron density of the amino ligand.

不饱和醛和酮在水相中常压选择性加氢成不饱和醇的研究

采用n功能化氨基配体稳定的钌配合物（o-PPh2C6H4NHMe）[(CH2NHR)2]RuCl2 （R = H, Me, Et）和（o-PPh2C6H4NMe2）[(CH2NHEt)2]RuCl2，具有广泛的底物相容性和优异的功能耐受性，实现了水相常压下不饱和醛和酮加氢成具有保留C=C键的相应醇的绿色催化体系。o-PPh2C6H4NHMe和（CH2NHEt）2之间的结构协同作用使性能得到增强，且与氨基配体的电子密度呈正相关。
