ASYMMETRIC CATALYSIS .4. HYDROSILYLATION OF ACETOPHENONE WITH PYRROLINE-2,5-DIONE MODIFIED [RH(COD)CL](2) CATALYSTS
The reaction of dichloromaleimides with optically active amines affords chiral pyrrolin-2,5-diones. The diamines are C-13-NMR-spectroscopically characterized. In addition, the molecular structure of 1-(R)-menthyl-3-(R)-menthylamino-4-phenylamino-pyrrolin-2,5-dion (12) has been determined by X-ray crystallography. The pyrrolin-2,5-diones have been applied as planar, chiral N,N-ligands to modify the [Rh(COD)Cl](2) catalyst in the asymmetric hydrosilylation reaction of acetophenone. However, the optical induction observed for this reaction are poor for N,N-ligands as compared to the corresponding P,P-ligands.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 29968-78-3, you can contact me at any time and look forward to more communication. Quality Control of 4-Nitrophenylethylamine hydrochloride.
