| 摘要 |
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, RuH2L<1>3 (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 L<1> is a neutral electron pair donor ligand independently selected from: H2, N2, nitriles, amines, alcohols, ethers, esters, amides, alkenes, alkynes, aldehydes, ketones and imines. |
