一般描述
The product is an air-stable and non-hygroscopic Solvias chiral phosphine ligand.
应用
Walphos SL-W001-2, in the presence of a ruthenium catalyst may be used as a ligand in the following processes:
- Asymmetric hydrogenation of IPCA-D, a cinnamic acid derivative.
- Addition of 3,5-difluorophenylketimine to 4-methoxyphenylboronic acid to form the corresponding tertiary substituted cyclic sulfamate derivative with high enantioselctivity.2
包装
Bottomless glass bottle. Contents are inside inserted fused cone.

Two representative Walphos analogues with an achiral 2,2″-biferrocenediyl backbone were synthesized. These diphosphine ligands were tested in the rhodium-catalyzed asymmetric hydrogenation of several alkenes and in the ruthenium-catalyzed hydrogenation of two ketones. The results were compared with those previously obtained
