Related Products of 221012-82-4. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine, is researched, Molecular C38H34N2O4P2, CAS is 221012-82-4, about Asymmetric amidocarbonylation of aldehyde and acetamide catalyzed by chiral palladium or rhodium complexes. Author is Xing, Ai-ping; Wang, Lai-lai; Kwok, Waihim.
The in situ prepared chiral catalyst of Pd/unchelating bidentate phosphine ligand L1 (DPPFF), bipyridine bidentate phosphine ligand L2 (P-PHOS), and bidentate phosphine ligand L3 ((S, Rp) -BPPF), and Rh/phosphite ligands L4-L6, have been applied in amidocarbonylation of cyclohexanecarboxaldehyde or phenylacetaldehyde. Pd/bipyridine bidentate phosphine ligand L2 gave the enantioselectivity 25% (S) and the yield 11% in amidocarbonylation of phenylacetaldehyde, When Pd/unchelating bidentate phosphine ligand L1 was employed in asym. amidocarbonylation of cyclohexanecarboxaldehyde, the enantioselectivity 4.3% (S) and the yield 15% were received.
