A palladium-catalyzed asym. synthesis of silicon-stereogenic 5,10-dihydrophenazasilines was developed that proceeds via an unprecedented enantioselective 1,5-palladium migration. High enantioselectivity was achieved by employing 4,4′-bis(trimethylsilyl) (R)-Binap as the chiral ligand, and a series of mechanistic investigations were carried out to probe the catalytic cycle of this process. In the experiment, the researchers used many compounds, for example, (1R)-1-[Bis(4-methoxy-3,5-dimethylphenyl)phosphino]-2-[(1R)-1-(dicyclohexylphosphino)ethyl]ferrocene (cas: 360048-63-1Synthetic Route of C42H56FeO2P2).
(1R)-1-[Bis(4-methoxy-3,5-dimethylphenyl)phosphino]-2-[(1R)-1-(dicyclohexylphosphino)ethyl]ferrocene (cas: 360048-63-1) belongs to chiral phosphine ligands. During the past two decades, tertiary phosphine catalysts have been applied extensively in a wide range of carbon–carbon and carbon–heteroatom bond-forming transformations. Asymmetric catalytic performance is determined not only by the metal center but also by the chiral ligand selected.Synthetic Route of C42H56FeO2P2
