Quality Control of (S)-3,3′-Dibromo-1,1′-bi-2-naphthol. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: (S)-3,3′-Dibromo-1,1′-bi-2-naphthol, is researched, Molecular C20H12Br2O2, CAS is 119707-74-3, about Iridium-Catalyzed Asymmetric Allylic Amination Reactions with N-Aryl Phosphoramidite Ligands. Author is Zhang, Xiao; Liu, Wen-Bo; Cheng, Qiang; You, Shu-Li.
N-aryl phosphoramidite ligands were synthesized, and the Ir complexes derived from these novel ligands were proven to be efficient catalysts for asym. intermol. allylic amination reactions. This C-N bond forming process readily accommodates a diverse range of amines and allylic carbonates, especially for the previously challenging ortho-substituted cinnamyl substrates. Also, isolation and characterization of the corresponding (π-allyl)-Ir complex K1 reveal that the active iridacycle is generated through a C(sp2)-H bond insertion of tetrahydroquinoline of the ligand.
