Reference of 52522-40-4, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 52522-40-4, molcular formula is C52H43Cl3O3Pd2, introducing its new discovery.
Highly diastereo- and enantioselective palladium-catalyzed[3+2] cycloaddition of vinyl aziridines and alpha,beta-unsaturated ketones
A palladium-catalyzed asymmetric [3+2] cycloaddition reaction of vinylaziridines with alpha,beta-unsaturated ketones, wherein the alkenes have a single activator, is realized in high diastereo- and enantioselectivity, thus affording 3, 4-disubstituted pyrrolidines in high yields with excellent ee values. The introduction of a methyl group at C1 of the vinyl group the vinylaziridines greatly improves the stereochemistry of the reaction. A plausible transition state is proposed.
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 52522-40-4 is helpful to your research. Reference of 52522-40-4
