In some cases, the catalyzed mechanism may include additional steps.In a article, 18671-97-1, molcular formula is C8H4Cl2N2, introducing its new discovery.
A new synthesis of 1,5-dihydropyridazino[3,4-b]quinoxalines and 2-(pyrazol-4-yl)quinoxalines
The reaction of 6-chloro-2-(1-methylhydrazino)quinoxaline 1-oxide 3 with acetylenedicarboxylates gave the 8-chloro-1-metoyl-1,5-dihydropyridazino[3,4-b]quinoxaline-3,4-dicarboxylates 4a,b and 2-(pyrazol-4-yl)quinoxaline 1-oxides 5a,b. The formation of compounds 4a,b would follow the 1,3-dipolar cycloaddition reaction, subsequent 1,2-hydrazino migration, and then dehydrative cyclization, while the production of compounds 5a,b would proceed via the addition of the hydrazino group to acetylenedicarboxylate leading to the construction of a pyrazole ring, followed by rearrangement of the pyrazole ring. Compounds 5a,b were deoxidized with phosphoryl chloride/N,N-dimethylformamide to change into the 4-(quinoxalin-2-yl)pyrazole-3-carboxylates 8a,b.
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 18671-97-1 is helpful to your research. Related Products of 18671-97-1
