The present invention relates to processes for the reduction by hydrogenation, using molecular H2, of a substrate containing one or two esters, or lactones, functional groups into the corresponding alcohol, or diol, with the process being carried out in the presence of a base and at least one catalyst or pre-catalyst in the form of a ruthenium complex, wherein the ruthenium is coordinated by a diphosphine bidentate ligand (PP ligand) and a diamino bidentate ligand (NN ligand) that includes at least one substituted α-carbon and one primary amine as one of the coordinating atoms.
本发明涉及一种使用分子氢(H2)对含有一或两个
酯类或
内酯类官能团的底物进行加氢还原的方法,使其转化为相应的醇或二醇。该方法在碱存在下,至少使用一种
钌配合物催化剂或前催化剂,其中
钌由
二膦双齿
配体(PP
配体)和一种含有至少一个取代α-碳和一个主要胺基作为配位原子的二胺双齿
配体(NN
配体)配位。
