Electric Literature of 52010-22-7, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.52010-22-7, Name is 4-Chlorophthalide, molecular formula is C8H5ClO2. In a Article，once mentioned of 52010-22-7
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.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 52010-22-7
