Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.6372-42-5, Name is Cyclohexyldiphenylphosphine, SMILES is C1CCC(CC1)P(C1=CC=CC=C1)C1=CC=CC=C1, belongs to chiral-phosphine-ligands compound. In a document, author is Romero-Arenas, Antonio, introduce the new discover, HPLC of Formula: C18H21P.
Ir-Catalyzed Atroposelective Desymmetrization of Heterobiaryls: Hydroarylation of Vinyl Ethers and Bicycloalkenes
A highly regio-, diastereo-, and enantioselective, scalable Ir-catalyzed hydroarylation of electron-rich acyclic and tensioned cyclic olefins with heterobiaryls is described. The reaction of acyclic vinyl ethers, dihydrofuran, and norbornenes with a variety of aryl isoquinoline, quinazoline, and picoline derivatives takes place with simultaneous installation of central and axial chirality, reaching complete branched/linear or exo/endo ratios and excellent diastereo- and enantiomeric excesses when in situ formed [Ir-I/Tol-SDP] or [Ir-I/Tol-BINAP] complexes are used as the catalysts. Deuterium labeling experiments and a comprehensive computational study suggest that, despite fast double bond migratory insertion into Ir-H, the reaction proceeds through a modified Chalk-Harrod mechanism, starting with selectivity-determining insertion into Ir-C-Aryl. The regioselectivity is controlled by the electron-donating alkoxy group, whereas diastereo- and enantioselectivity have a complex origin, which depend on the relative orientation of the alkoxy group and the establishment of adequate pi-pi interactions between the biaryl and the phosphine.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 6372-42-5 is helpful to your research. HPLC of Formula: C18H21P.
