50777-76-9. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 50777-76-9, Name is 2-(Diphenylphosphino)benzaldehyde. In a document type is Article, introducing its new discovery.
A New Phosphine-Amine-Oxazoline Ligand for Ru-Catalyzed Asymmetric Hydrogenation of N-Phosphinylimines
A series of chiral phosphine-amine-oxazoline (PAO) ligands with an NH moiety were synthesized and applied to the ruthenium-catalyzed asymmetric hydrogenation of N-phosphinylimines. The ligand bearing phenyl groups at the phosphorus moiety and isopropyl at the oxazoline moiety exhibits good activity and excellent enantioselectivity (up to 99% ee). This catalytic system provides an efficient and mild approach to access enantioriched amines.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 50777-76-9, help many people in the next few years., 50777-76-9
