This invention relates to a catalyst for use in the hydrogenation of unsaturated substrates, especially organic nitriles. The catalyst comprises at least one ruthenium complex having the formula, RuH2L13 (PR3) wherein:
PR3 is an organophosphorus ligand;
each R is a substituent independently selected from: H, R', OR', OSiR'3, NH2, NHR' and NR'2;
each R' is independently selected from: a hydrocarbyl group, and an assembly of at least two hydrocarbyl groups connected by ether or amine linkages; and
each L1 is a neutral electron pair donor ligand independently selected from: H2, N2, nitriles, amines, alcohols, ethers, esters, amides, alkenes, alkynes, aldehydes, ketones and imines.
本发明涉及一种用于不饱和底物,特别是有机腈氢化的催化剂。该催化剂包括至少一种钌络合物,其式为 RuH2L13 (PR3) 其中:
PR3 是有机磷配体;
每个 R 是独立选自以下各项的取代基:H、R'、OR'、OSiR'3、NH2、NHR' 和 NR'2
每个 R'独立选自:烃基,以及通过醚或胺连接的至少两个烃基的组合;以及
每个 L1 都是中性电子对供体配体,独立选自:H2、N2、腈、胺、醇、醚、酯、酰胺、烯、炔、醛、酮和亚胺。
