New Advances in Chemical Research, May 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry.Quality Control of 2,3-Dichloro-6,7-dimethylquinoxaline, In a article, mentioned the application of 63810-80-0, Name is 2,3-Dichloro-6,7-dimethylquinoxaline, molecular formula is C10H8Cl2N2
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.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 63810-80-0, help many people in the next few years.category: quinoxaline
