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.Product Details of 49679-45-0, In a article, mentioned the application of 49679-45-0, Name is Ethyl 3-chloroquinoxaline-2-carboxylate, molecular formula is C11H9ClN2O2
Chloropyrimidines 2, 3 and Chlorquinazolines 9, 10, after conversion into trimethylammonio derivatives 4, 5, 11, 12, react with tetraethylammonium cyanide 1a under very mild conditions to give pyrimidine carbonitriles 6, 7 and quinazoline carbonitriles 13, 14.Direct synthesis of quinoxaline carbonitriles 19 is possible by reaction of chloroquinoxalines 15, 18 with 1a.
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 49679-45-0, help many people in the next few years.Product Details of 49679-45-0
