First performed by Justus von Liebig in 1838, [1] it is the first reported example of a rearrangement reaction. [2] It has become a classic reaction in organic synthesis and has been reviewed many times before. [3] [4] [5] It can be viewed as an intramolecular redox reaction, as one carbon center is oxidized while the other is reduced. Scheme 1.
Benzilic acid is an organic compound with formula C 14 H 12 O 3 or (C 6 H ... which is transformed to the product by the benzilic acid rearrangement reaction. ...
The benzyl cation or phenylcarbenium ion is the carbocation with formula C 6 H 5 CH + 2; the benzyl anion or phenylmethanide ion is the carbanion with the formula C 6 H 5 CH − 2. None of these species can be formed in significant amounts in the solution phase under normal conditions, but they are useful referents for discussion of reaction ...
In organic chemistry, benzoyl (/ ˈ b ɛ n z oʊ ɪ l /, BENZ-oh-il) [1] is the functional group with the formula −COC 6 H 5 and structure −C(=O)−C 6 H 5. [2] [3] It can be viewed as benzaldehyde missing one hydrogen. The benzoyl group has a mass of 105 amu. The term "benzoyl" should not be confused with benzyl, which has the formula − ...
Benzil (i.e. Bz 2, systematically known as 1,2-diphenylethane-1,2-dione) is the organic compound with the formula (C 6 H 5 CO) 2, generally abbreviated (PhCO) 2. This yellow solid is one of the most common diketones. Its main use is as a photoinitiator in polymer chemistry. [4]
Benzyl chloride, or α-chlorotoluene, is an organic compound with the formula C 6 H 5 CH 2 Cl. This colorless liquid is a reactive organochlorine compound that is a widely used chemical building block .
The reaction constant, or sensitivity constant, ρ, describes the susceptibility of the reaction to substituents, compared to the ionization of benzoic acid. It is equivalent to the slope of the Hammett plot. Information on the reaction and the associated mechanism can be obtained based on the value obtained for ρ. If the value of:
In pure compounds, reactivity is regulated by the physical properties of the sample. For instance, grinding a sample to a higher specific surface area increases its reactivity. In impure compounds, the reactivity is also affected by the inclusion of contaminants. In crystalline compounds, the crystalline form can also affect reactivity. However ...
