일반 설명
(R,R)-(-)-2,3-Bis(tert-butylmethylphosphino)quinoxaline is an air-stable C2-symmetric P-stereogenic phosphine ligand.[1]
애플리케이션
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.[2]
특징 및 장점
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
