일반 설명

The product is an air-stable and non-hygroscopic Solvias chiral phosphine ligand.

애플리케이션

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

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
