New research progress on 80-07-9 in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 80-07-9, Name is 4,4′-Sulfonylbis(chlorobenzene), formurla is C12H8Cl2O2S. In a document, author is Dawsey, Anna C., introducing its new discovery. COA of Formula: C12H8Cl2O2S.
A variety of substituted spiro(benzoisothiazole-pyrazoles) have been prepared by the condensation of dilithiated C(alpha),N-carboalkoxyhydrazones with lithiated methyl 2-(aminosulfonyl)benzoate followed by the cyclization of intermediates with acetic anhydride, which also resulted in spiro N-acetylated products when carbomethoxyhydrazones or carboethoxyhydrazones were used, and spiro, NH products when carbo-tert-butoxyhydrazones were used.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. In my other articles, you can also check out more blogs about 80-07-9. COA of Formula: C12H8Cl2O2S.
