One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, HPLC of Formula: C51H42O3Pd2, 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
Enantioselective addition of diethylzinc to aromatic aldehydes catalyzed by chiral BINOL-functionalized nanoporous graphene oxides
The supporting material on which an asymmetric catalytic reaction takes place has proved to be an important component which could influence the efficiency and sometimes enantioselectivity of a heterogeneous asymmetric reaction. On the other hand, graphene oxide (GO) has attracted broad attentions because of its unique characteristics and potential applications in many fields. However, GOs have been rarely employed as the supporting materials for heterogeneous catalytic reactions, especially those enantioselective reactions. Herein, a new type of GO-based heterogeneous catalyst was prepared for enantioselective addition of diethylzinc to aromatic aldehydes. To produce this GO catalyst, commercial GO was firstly oxidized in an acidic environment to make nanoporous GOs and then enantiopure (R) or (S)-NH2-BINOLs were attached (covalently) onto the nanoporous GOs, and this GO-BINOL was subsequently treated by using Ti(OiPr)4. The as-prepared GO-BINOL-Ti catalyst displayed good reactivity (99%) and modest enantioselectivity (45% ee) in the following asymmetric addition reactions. We expect this preliminary demonstration could inspire the research by using GO as heterogeneous catalytic supports and could improve the enantioselectivity later.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C51H42O3Pd2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 52409-22-0, in my other articles.
