Reference of (S)-3,3′-Dibromo-1,1′-bi-2-naphthol. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: (S)-3,3′-Dibromo-1,1′-bi-2-naphthol, is researched, Molecular C20H12Br2O2, CAS is 119707-74-3, about Lewis Acid Catalysis and Ligand Exchange in the Asymmetric Binaphthol-Catalyzed Propargylation of Ketones. Author is Grayson, Matthew N.; Goodman, Jonathan M..
1,1′-Bi-2-naphthol (BINOL)-derived catalysts catalyze the asym. propargylation of ketones. D. functional theory (DFT) calculations show that the reaction proceeds via a closed six-membered transition structure (TS) in which the chiral catalyst undergoes an exchange process with the original cyclic boronate ligand. This leads to a Lewis acid type activation mode, not a Bronsted acid process, which accurately predicts the stereochem. outcome observed exptl.
