New Advances in Chemical Research, May 2021. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. 148231-12-3, In a article, mentioned the application of 148231-12-3, Name is 5,8-Dibromoquinoxaline, molecular formula is C8H4Br2N2
(Chemical Equation Presented) Two series of aniline oligomers bearing fused heterocycles as an electron-acceptor unit were synthesized. They consist of aniline or its derivatives as an electron donor and benzothiadiazole (BT) or quinoxaline (QX) as an electron-acceptor unit. Benzothiadiazoles 1-3 were synthesized by palladium-catalyzed amination. Quinoxalines 4-6 were prepared by palladium-catalyzed amination or transformation from the benzothiadiazoles. These compounds showed a HOMO-LUMO gap smaller than those of their analogues such as thiophene-substituted BT/QXs. Cyclic voltammetry revealed that the electrochemical behavior is dependent on the position of the acceptor heterocycle. Chemical oxidation with Ag2O afforded the corresponding 1,4-quinonediimine derivatives as an E,E-isomer, stereoselectively. As for the BT pentamer analogues 2 and 3, the first oxidation selectively occurred at the amino group adjacent to the benzothiadiazole unit, giving the regiospecific half-oxidized derivatives. Furthermore, the fully oxidized derivative 24 was isolated and characterized.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 148231-12-3
