Zhang, Dao published the artcileEffect of the Dihedral Angle of Biaryl-Bridged Bis(N-Heterocylic Carbene) Ligands on Enantioselectivity in Pd-Catalyzed Asymmetric Aryl-Aryl Cross-Coupling, COA of Formula: C11H10O, the publication is Organometallics (2022), 41(6), 811-819, database is CAplus.
New biaryl-bridged bis(N-heterocylic carbene) Pd complexes were synthesized and applied in asym. Suzuki cross-coupling of aryl halide and aryl boronic acid. X-ray crystallog. studies of square-planar Pd complexes of four of these bis(NHC) ligands revealed that the dihedral angle of the bridging biaryl moiety depends on its identity and lies 79.65-92.69°. A linear correlation between the dihedral angle in these Pd complexes and cross-coupling enantioselectivity is 1st reported. Also, larger Ccarbene-Pd-Ccarbene bite angles lead to increased enantioselectivity in a 1st fast and then slow growing tendency.
