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.Synthetic Route of 2213-63-0, In a article, mentioned the application of 2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2
The reactivity of 2,3-dialkynylquinoxalines towards electrophiles (Br 2, I2, ICI, NBS, HBr) has been studied. All tested reactions, except one with HBr, start with the addition of an electrophile to the carbon-carbon triple bond that promotes further 5-exo-dig carbocyclization ultimately yielding a mixture of stereoisomeric cyclopenta[b]quinoxaline derivatives. The nature of substituents on the C=C bonds of the starting molecule influence the stereochemical result of the reaction. The ratio of isomeric cyclization products also depends on the electrophile used. ortho-Dialkynylbenzenes and ortho-dialkynylquinoxalines demonstrate rather similar reactivity towards halogen electrophiles, but differ in their reactions with hydrobromic acid, which is caused by the basic nature of the aza group of the quinoxaline substrate.
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 2213-63-0 is helpful to your research. Synthetic Route of 2213-63-0
