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.

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 ...
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 .
Benzylpotassium is an organopotassium compound with the formula C 6 H 5 CH 2 K, an orange powder. Like organo-alkali metal reagents in general, benzyl potassium is highly reactive, so much so that it reacts with most solvents. It is highly air sensitive.
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:
Dewar's reactivity number is then defined as = (+). Clearly, the smaller the value of N i, the less the destabilization energy in going towards the transition state and the more reactive the site. Thus, by computation of the molecular orbital coefficients it is possible to evaluate Dewar's number for all the sites and establish which one will ...
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]
