Functionalization of BINOL-mono-PHOS achieved the Cu-catalyzed highly asymmetric conjugateaddition of organozincreagents to enones. The incorporation of a bulky hydroxy group at the 3′-position o...
neighbouring lithium‐promoted [1,2]‐Wittig rearrangement proceeding with excellent diastereoselectivity and enantioselectivity is the key process in this approach. Also, in the catalytic alkynylation of aromatic aldehydes with terminal alkynes, the combination of these Ar‐BINMOL‐Phos ligands with dimethylzinc was found to be an effective catalyst system to afford predominantly the S‐configured propargylic
The synthesis and characterization of a novel chiral phosphine–phosphoric acid ligand, (R)-3-diphenylphosphino-1,1′-binaphthyl-2,2′-diyl hydrogenphosphate (2) and its rhodium(I) complexes are described. The single-crystal X-ray diffraction analysis of 2 showed the intermolecular hydrogen-bonding network of the phosphoric acid moiety. The reactions of 2 with [RhCl(cod)]2 in the presence of KOtBu or
