Keywords: benzodioxole diphosphinylbis preparation geometry acidity chiral ligand asym hydrogenation; ketone fluorinated asym hydrogenation; alc beta functionalized asym synthesis; rhodium complex diphosphine IR spectra; diphosphine atropisomeric dihedral angle; diselenide atropisomeric diphosphine NMR spectra.They researched the compound: (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole( cas:503538-69-0 ).Synthetic Route of C38H24F4O4P2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:503538-69-0) here.
Both enantiomers of difluorphos I were synthesized and their stereoelectronic features were evaluated in theor. and exptl. studies. The unusual π acidity of I explains the excellent results obtained with it in ruthenium-mediated asym. hydrogenation of fluorinated β-functionalized ketones. These results are better than those obtained with other biphenyl-based diphosphines.
Here is just a brief introduction to this compound(503538-69-0)Synthetic Route of C38H24F4O4P2, more information about the compound((R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole) is in the article, you can click the link below.
