结构式
基本信息
| Empirical Formula【经验(实验)分子式】 | C32H22F10N2O2 |
| Molecular weight | 656.51 |
| Application【应用】 | Developed by Albrecht Berkessel′s lab, this is the first catalyst system that allows catalytic enantioselective epoxidation of non-conjugated terminal double bonds with hydrogen peroxide as the oxidant. Eradicating multiple steps and kinetic resolution, this chiral ligand, when used with Ti(OiPr)4 provides a one-step route to enantiopure epoxides that are important intermediates for synthesis of bioactive compounds. Catalyst is recyclable under some conditions. For best results, pentafluorobenzoic acid (P5360) or tetra-n-butylammonium hydrogensulfate (155837) is recommended as a co-catalyst. |
