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.

Abstract
The efficient preparation of long-chain amines via a one-step transfer-hydrogenation/reductive-amination reaction (THRA) of polyenals has been achieved. This strategy, which combines transfer hydrogenation and reductive amination, significantly enhances the synthetic efficiency of amino compounds. Additionally, this protocol offers a practical method for carbon-chain elongation/amination to construct long-chain amino compounds. The reaction system exhibits remarkable versatility in substrate scope using a non-noble ruthenium catalyst with formate and isopropanol as hydrogen sources, making it an appealing method for drug synthesis and molecular modification.
