Synthetic Route of 50777-76-9, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 50777-76-9, Name is 2-(Diphenylphosphino)benzaldehyde, molecular formula is C19H15OP. In a Article，once mentioned of 50777-76-9
Herein, we report the use of phosphinoazomethinylate salts as chiral efficient ligands for the copper-catalyzed asymmetric conjugate addition (ACA) of dialkylzinc to various enones. These tridentate P,N,O ligands are straightforwardly obtained in a one-step procedure from commercially available enantiopure alpha-aminoacids. Performing the conjugate addition in the greener AcOEt solvent, high enantioselectivities were reached for both cyclic and acyclic enones ranging between 72% to 98% ee and 96% to >99%, respectively. The 2/1 Cu/ligand ratio required to obtain high enantioselectivities, led us to envisage a copper-copper bi-metallic catalytic system for this transformation.
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 50777-76-9 is helpful to your research., Reference of 50777-76-9
