Electric Literature of 1445085-55-1, 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, 1445085-55-1, molcular formula is C46H62NO3PPdS, introducing its new discovery.
Efficient and Functional-Group-Tolerant Synthesis of Substituted Furans through the Pd-Catalyzed 5-exo-dig Cyclization/Coupling of gamma-Acetylenic beta-Keto Esters with (Hetero)Aryl Bromides
We report an efficient protocol for the synthesis of 2,3,5-trisubstituted furans through the reaction of readily available gamma-acetylenic beta-keto esters with aryl and heteroaryl bromides. The reaction, which involves a 5-exo-dig cyclization, coupling, and isomerization of a double bond, proceeds smoothly with very low catalyst loading (0.1 mol-%), and shows excellent functional-group tolerance.
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 1445085-55-1 is helpful to your research. Electric Literature of 1445085-55-1
