Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Angewandte Chemie, International Edition called Supramolecular Control of Ligand Coordination and Implications in Hydroformylation Reactions, Author is Bellini, Rosalba; Chikkali, Samir H.; Berthon-Gelloz, Guillaume; Reek, Joost N. H., which mentions a compound: 119707-74-3, SMILESS is OC1=C(Br)C=C2C=CC=CC2=C1C3=C4C=CC=CC4=CC(Br)=C3O, Molecular C20H12Br2O2, Application In Synthesis of (S)-3,3′-Dibromo-1,1′-bi-2-naphthol.
The authors present a new class of chiral monodentate phosphoramidite ligands based on the bis(naphthol) skeleton. The coordination mode of the monodentate phosphoramidite ligands in trigonal-bipyramidal tricarbonyl rhodium hydride phosphoramidite complexes can be switched from equatorial to axial by a unique supramol. pseudo encapsulation, providing a new tool to control the activity and selectivity of a transition metal catalyst. In situ high-pressure 1H and 31P NMR and IR studies under hydroformylation conditions demonstrate the formation of the 1st Rh hydride complex in which the P donor atom of the ligand is trans to the hydride, but only after coordination of Zn(II) porphyrin moieties to the pyridyl moieties of the ligand. In absence of these Zn(II) porphyrins, the common mono-ligated Rh hydrido complexes are formed with the ligand in the equatorial plane, in cis orientation to the hydride. The supramol. change to the unusual coordination is reflected in higher activity and selectivity when these complexes are applied to the very challenging asym. hydroformylation of unfunctionalized internal alkenes.
