Electric Literature of 102308-43-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 102308-43-0, 4-Bromo-2-benzofuran-1[3H]-one, introducing its new discovery.
17O chemical shift data (natural abundance) for 3-substituted phthalic anhydrides and 4- and 7-substituted phthalides in acetonitrile at 75 deg C are reported.Steric interactions of substituents ortho to the carbonyl groups result in deshielding effects (9-22 ppm) relative to parent compounds regardless of the electronic character of the substituents.Factors contributing to the deshielding effects are discussed.The relationship between 17O chemical shifts and regiochemistry of the phthalic anhydrides is discussed.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 102308-43-0. In my other articles, you can also check out more blogs about 102308-43-0
