摘要:
The present invention relates to a process for the asymmetric hydrogenation of imines with hydrogen under elevated pressure in the presence of a catalyst system. In particular the present invention relates to the use of the said catalytic system for the enantioselective hydrogenation of prochiral ketimines to asymmetric amines leading to the formation of herbicides.
