A process is provided for the hydrogenation of imines with hydrogen under elevated pressure in the presence of iridium complexes as catalysts and one or more co-catalysts selected among compounds comprising a carbon-halogen bond. Further provided are novel ligands and metal complexes thereof useful for the catalytic hydrogenation of imines with hydrogen. The novel ligands are compounds of the formula (VII) or formula (VIII) in the form of racemates, mixtures of stereoisomers or optically pure stereoisomers, wherein the radicals are as defined in the specification.
提供了一种在铱络合物存在下,在高压下利用氢气对亚胺进行加氢的方法,其中选择的一个或多个辅催化剂为包含碳-卤素键的化合物。还提供了用于催化亚胺与氢气加氢的新型配体和金属络合物。这些新型配体是根据式(VII)或式(VIII)的化合物,以外消旋体、立体异构体混合物或光学纯立体异构体的形式存在,其中基团如规范中所定义。
