The synthesis of phosphine-imidazolyl ligands 1 and 2 in good yields is presented. In combination with [{Ru(benzene)Cl2}2], ligands 1 c and 1 e formed efficient catalyst systems for the selective hydrogenation of various carboxylic esters into their corresponding primary alcohols. Furthermore, the structures of four ruthenium complexes with ligands 1 b, 1 c, 1 d, and 1 e were determined by X-ray crystallography, which showed the formation of different coordination modes depending on the ligand structure.

A new reduction system employing N-methylpiperazine-modified sodium bis(2-methoxyethoxy)aluminum hydride (NMP-SMEAH) for the conversion of aromatic diesters to dialdehydes is described. The method is plain and efficient, and can be carried out under mild and operationally simple conditions applicable for large scale productions.
