Abstract
The reaction of dichloromaleimides with optically active amines afford s chiral pyrrolin-2,5-diones. The diamines are C-13-NMR-spectroscopica lly characterized. In addition, the molecular structure of 3-(R)-menth ylamino-4-phenylamino-pyrrolin-2,5-dion (12) has been determined by X- ray crystallography. The pyrrolin-2,5-diones have been applied as plan ar, chiral N,N-ligands to modify the [Rh(COD)Cl](2) catalyst in the as ymmetric hydrosilylation reaction of acetophenone. However, the optica l induction observed for this reaction are poor for N,N-ligands as com pared to the corresponding P,P-ligands.
