The conversion of benzil (α-diketone) into the salt of α-hydroxy acid by means of base treatment is generally referred to as the benzilic acid rearrangement or benzil-benzilic acid rearrangement. This rearrangement is normally carried out in the favored solvents of water and aqueous ethanol, an...

Benzilic acid rearrangement « on: October 19, 2004, 02:09:40 AM » I have a question about benzilic acid rearrangement. I know how benzil can react with potassium hydroxide to produce benzilic acid, but I don't know the mechanism that is used in the production of its side product,...
the 1,2-rearrangement of 1,2-diketones to generate -hydroxy–carboxylic acids using a base is known as the benzilic acid rearrangement. the interaction of benzil with potassium hydroxide to create benzilic acid gives this reaction its name. it was the first known example of a rearrangement ...
Reaction of benzil with HO- in the chemical ionization source of a triple-analyser mass spectrometer forms a [benzl + HO-] ion. This ion, upon collisional activation, gives a mass spectrum identical to that obtained from deprotonated benzilic acid under the same experimental conditions....
