Acyloin

Acyloins are a class of compounds of organic chemistry, possessing a keto group and a hydroxyl group on adjacent carbon atoms. It is therefore to α -hydroxy ketones. A special form of the benzoins, in which both radicals R1 and R2 are aryl groups (e.g., phenyl groups). Acyloins form intramolecular hydrogen bonds.

Synthetic acyloins are accessible through a acyloin condensation. Furthermore, the Rubottom oxidation provides the ability to figure out silyl ethers of enols acyloins. Aromatic acyloins can be represented by a benzoin addition.

In the alkaline form acyloins Endiolatanionen which have a reducing effect ( eg Fehling's solution) and oxidized to 1,2- diketones. By reduction of acyloins obtained vicinal diols.
