The present invention relates to processes for the reduction by hydrogenation, using molecular H2, of a C5-C20 substrate containing one or two aldehydes functional groups into the corresponding alcohol or diol, characterized in that said process is carried out in the presence of —at least one catalyst or pre-catalyst in the form of a ruthenium complex having a coordination sphere of the N2P2O2, wherein the coordinating atoms N2 are provided by a first bidentate ligand, the coordinating atoms P2 are provided by a second bidentate ligand and the coordinating atoms O2 are provided by two non-linear carboxylate ligands; and—optionally of an acidic additive.
本发明涉及使用分子氢进行还原的C5-C20底物的过程,该底物含有一个或两个醛官能团,并转化为相应的醇或二元醇。其特征在于,在至少一种催化剂或前催化剂的存在下进行该过程,所述催化剂或前催化剂以N2P2O2的配位球形形式存在,其中协同原子N2由第一双齿
配体提供,协同原子P2由第二双齿
配体提供,协同原子O2由两个非线性
羧酸盐
配体提供;以及可选的酸性添加剂。
