One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, COA of Formula: C9H6N2O, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 130345-50-5, Name is Quinoxaline-6-carbaldehyde, molecular formula is C9H6N2O
Meta C-H Arylation of Electron-Rich Arenes: Reversing the Conventional Site Selectivity
Controlling site selectivity of C-H activation without using a directing group remains a significant challenge. While Pd(II) catalysts modulated by a mutually repulsive pyridine-type ligand have been shown to favor the relatively electron-rich carbon centers of arenes, reversing the selectivity to favor palladation at the relatively electron-deficient positions has not been possible. Herein we report the first catalytic system that effectively performs meta C-H arylation of a variety of alkoxy aromatics including 2,3-dihydrobenzofuran and chromane with exclusive meta site selectivity, thus reversing the conventional site selectivity governed by native electronic effects. The identification of an effective ligand and modified norbornene (NBE-CO2Me), as well as taking advantage of the statistics, are essential for achieving the exclusive meta selectivity.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C9H6N2O, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 130345-50-5, in my other articles.
