• Unexpected Role of Anionic Ligands in the Ruthenium-Catalyzed Base-Free Selective Hydrogenation of Aldehydes

  Bigger and better: The replacement of anionic chloride ligands in Noyori‐type [(diamine)(diphosphine)RuCl2] catalysts with bulky carboxylate ligands enabled the efficient selective hydrogenation of a variety of aldehydes under base‐free conditions (see scheme). Turnover numbers of up to 100 000 were reached in the presence of a bulky carboxylic acid co‐catalyst. This type of catalytic system probably

  更大，更好：用笨重的羧酸盐配体取代Noyori型[[二胺]（二膦）RuCl 2 ]催化剂中的阴离子氯化物配体，可以在无碱条件下有效地选择性氢化多种醛（参见方案）。在庞大的羧酸助催化剂的存在下，营业额高达100,000。这种类型的催化系统可能通过内球机理运行。

  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 alcohols 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 N1P3O2, wherein the coordinating atom N and one coordinating atom P are provided by a first bidentate ligand, and the two other 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.
