The Cu-catalyzed, one-pot tandem (asym.) borylation of β-chloroalkyl aryl ketones via the in situ generated acyclic enones with bis(pinacolato)diboron was achieved efficiently to reach up to 97% yield and 99% enantioselectivity for the formal sp3 C-Cl borylation products. The present methodol. provides an efficient alternative route to (chiral) alkylboron compounds In the experiment, the researchers used many compounds, for example, (R,R)-2,2′-Bis[(R)-(N,N-dimethylamino)(phenyl)methyl]-1,1′-bis(diphenylphosphino)ferrocene (cas: 174467-31-3Recommanded Product: 174467-31-3).
(R,R)-2,2′-Bis[(R)-(N,N-dimethylamino)(phenyl)methyl]-1,1′-bis(diphenylphosphino)ferrocene (cas: 174467-31-3) 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. Chiral ligands coordinate to metal centers to create an asymmetric environment around the reaction centers, which eventually affects enantioselectivity and reaction rate.Recommanded Product: 174467-31-3
