Asymmetric fluorous catalytic systems with recovery of catalyst ligand by solid phase extraction |
| 摘要 |
<p>The present invention relates to a process for the recovery and the reuse of catalytic systems involving 1,1'-Bi-2-Naphthol (BINOL) and titanium tetraisopropoxide from reaction mixtures comprising organotin species. A further object of the invention is a method for catalyzing an asymmetric reaction in high conversion rate and enantioselectivity.</p> |
