R)-(-)-2,3-Bis(
tert-butylmethylphosphino)quinoxaline is an air-stable
C2-symmetric P-stereogenic phosphine ligand.
Air-Stable and Highly Efficient Chiral Ligands,
Efficient ligand exhibiting high levels of enantiocontrol in synthetic transformations ranging from metal-catalyzed 1,4-addition of arylboronic acids to alkylative ring opening to asymmetric hydrogenation.
100 mg in clear glass bottle
500 mg in amber glass bottle
Advantages of the QuinoxP* Ligands:
- It is not oxidized nor epimerized at ambient conditions in air
- Enantioselectivities are outstanding for various reaction paradigms
- Hydrogenations proceed under mild reaction conditions
- Low catalyst loadings yield high TONs
