New Advances in Chemical Research, May 2021. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. 1910-90-3, In a article, mentioned the application of 1910-90-3, Name is 6-Bromoquinoxaline-2,3(1H,4H)-dione, molecular formula is C8H5BrN2O2
An efficient one-pot reaction has been developed for the synthesis of 2,3-dichloroquinoxaline derivatives 3a?n. The reaction was performed in two steps via a silica gel catalyzed tandem process from o-phenylenediamine and oxalic acid, followed by addition of phosphorus oxychloride (POCl3). A variety of 2,3-dichloroquinoxalines have been obtained in good to excellent overall yields. Eight known compounds 3a?3h were characterized by IR, 1H-NMR, and mass spectroscopies. Compounds 3i?3n without spectroscopic data were characterized by IR, 1H-NMR, 13C-NMR, and mass spectroscopies.
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 1910-90-3 is helpful to your research. 1910-90-3
