Related Products of 4442-53-9, Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis.Enzyme inhibitors cause a decrease rate of an enzyme-catalyzed reaction to a specific portion of an enzyme and thus slowing a reaction . In an article, 4442-53-9, molcular formula is C9H8O4, introducing its new discovery.
Rh/Cu-Catalyzed Ketone beta-Functionalization by Merging Ketone Dehydrogenation and Carboxyl-Directed C-H Alkylation
An efficient Rh/Cu-catalyzed method has been developed for the direct beta-arylation or alkenylation of ketones using (hetero)aryl or alkenyl carboxylic acids as coupling partners. This direct ketone beta-functionalization reaction proceeded via the merging of Cu-catalyzed ketone dehydrogenative desaturation and Rh-catalyzed carboxyl-directed C-H alkylation, exhibiting a broad substrate scope for both coupling partners. TEMPO proved to be essential for both dehydrogenation process and generation of the active Rh catalyst for C-H activation.
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 4442-53-9 is helpful to your research. Related Products of 4442-53-9
