The invention relates to monocarbonyl complexes of ruthenium and osmium with bi- and tridentate nitrogen and phosphine ligands. The invention relates to methods for preparing these complexes and the use of these complexes, isolated or prepared in situ, as catalysts for reduction reactions of ketones and aldehydes both via transfer hydrogenation or hydrogenation with hydrogen.
                            这项发明涉及具有双齿和三齿氮
磷配体的
钌和
锇的单羰基配合物。该发明涉及制备这些配合物的方法以及将这些配合物(无论是分离的还是原位制备的)用作酮和醛的还原反应的催化剂,可以通过氢转移加氢或
氢气加氢进行。
