And the article was included in Journal of the American Chemical Society in 1999.Formula: C33H25OP This article mentions the following:
Reaction of 2-dimethylamino-2′-diphenylphosphino-1,1′-binaphthyl with (PhCN)2PdCl2 gave an unusual Cσ-Pd bonding mode complex I. The catalytic activity in allylic substitution, Hartwig-Buchwald Amination, and Suzuki coupling of I is described. The crystal structure of I and two related complexes were described. In the experiment, the researchers used many compounds, for example, (S)-(2′-Methoxy-[1,1′-binaphthalen]-2-yl)diphenylphosphine (cas: 134484-36-9Formula: C33H25OP).
(S)-(2′-Methoxy-[1,1′-binaphthalen]-2-yl)diphenylphosphine (cas: 134484-36-9) belongs to chiral phosphine ligands. Many phosphine-catalyzed reactions have been developed for the syntheses of various biologically important acyclic and cyclic molecules. Asymmetric variants of these reactions have evolved relatively slowly. Asymmetric catalytic performance is determined not only by the metal center but also by the chiral ligand selected.Formula: C33H25OP
