Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.18437-78-0, Name is Tris(4-fluorophenyl)phosphine, SMILES is FC1=CC=C(P(C2=CC=C(F)C=C2)C3=CC=C(F)C=C3)C=C1, belongs to chiral-phosphine-ligands compound. In a document, author is Kim, Junghoon, introduce the new discover, Name: Tris(4-fluorophenyl)phosphine.
Access to Enantioenriched Benzylic 1,1-Silylboronate Esters by Palladium-Catalyzed Enantiotopic-Group Selective Suzuki-Miyaura Coupling of (Diborylmethyl)silanes with Aryl Iodides
This work describes the palladium-catalyzed enantiotopic-group selective Suzuki-Miyaura cross-coupling of (diborylmethyl)silanes with aryl iodides. The combination of a Pd(TFA)(2) and rev-Josiphos-type ligand bearing a 3,5-bis(trifluoromethyl)phenyl as benzylic phosphine substituent in the presence of NaI as an additive and NaOMe as a base promotes the reaction to high efficiency and enantioselectivity. This method provides a convenient approach for synthesizing chiral benzylic 1,1-silylboronate esters from readily accessible reagents. Synthetic applications including stereospecific C-O, C-N, and C-C bond-forming reactions of boron group are also demonstrated.
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 18437-78-0 is helpful to your research. Name: Tris(4-fluorophenyl)phosphine.
