New research progress on 6825-20-3 in 2021.Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. 6825-20-3, Name is 3,6-Dibromo-9H-carbazole, molecular formula is , belongs to benzoxazole compound. In a document, author is Zheng, Ling-Li, Name: 3,6-Dibromo-9H-carbazole.
An efficient Palladium/Copper bimetallic co-catalyzed direct 2-arylation of benzoxazoles with aryl chlorides is presented. The Pd(OAc)(2)/Cul/NiXantphos-based catalyst enables the installation of various aryl and heteroaryl groups in good to excellent yields (75-99%). Preliminary mechanism investigation indicates that Pd/Nixantphos complex activates C-Cl bond of aryl chlorides via oxidative addition, and Cu/Nixantphos complex chelates with nitrogen atom to lower the pK(a) of the 2-H in benzoxazoles.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6825-20-3, in my other articles.
