The present invention relates to the field of catalytic hydrogenation and, more particularly, to the use of specific ruthenium catalysts, or pre-catalysts, in hydrogenation processes for the reduction of ketones and/or aldehydes into the corresponding alcohol respectively. Said catalysts are ruthenium complexes comprising a tetradentate ligand (L4) coordinating the ruthenium with: two nitrogen atoms, each in the form of a primary or secondary amine (i.e. a NH
2
or NH group) or N-alkyl imine functional groups (i.e. a C═N group), and two sulfur atoms, each in the form of thioether functional groups.
本发明涉及催化加氢领域,更具体地涉及在氢化过程中使用特定的钌催化剂或前驱体,用于将酮和/或醛还原为相应的醇。所述催化剂是包括一个四齿配体(L4)与钌配位的钌络合物,其中:两个氮原子,每个以一种主要或次要胺(即NH2或NH基团)或N-烷基亚胺功能基团(即C═N基团)的形式存在,以及两个硫原子,每个以硫醚功能基团的形式存在。
