One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Safety of Pd2(DBA)3, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 52409-22-0, Name is Pd2(DBA)3, molecular formula is C51H42O3Pd2
Palladium-Catalyzed Asymmetric Allylic Alkylations of Colby Pro-Enolates with MBH Carbonates: Enantioselective Access to Quaternary C?F Oxindoles
Owing to the innovative applications of fluorinated compounds in many areas of technology and medicine, methods for the preparation of C?F quaternary fluorine containing compounds are in extremely high demand. Here, we report the discovery of a general procedure for an SN2 reaction catalyzed by Pd/Ding-SKP-type ligands, and that occurs between Colby pro-enolates with MBH carbonates to afford the corresponding products featuring two consecutive stereogenic carbons, including a C?F quaternary stereogenic center. The reactions readily occur at ambient temperatures with high chemical yields and in excellent chemo-, diastereo- and enantioselective manners. This practically attractive stereochemical outcome, coupled with the operational simplicity and structural generality, bodes well for the synthetic application of this process in the preparation of a novel class of biologically relevant fluorine-containing compounds.
