* Reduction of acyloins give diols.
* Oxidation of acyloins give diones.
* α-hydroxy ketones give positive Tollens and Fehlings test.
* Some acyloins rearrange with positions swapped under the influence of base in the Lobry–de Bruyn–van Ekenstein transformation
* A similar reaction is the so-called Voigt amination where an acyloin reacts with a primary amine and phosphorus pentoxide to an α-keto amine:
* Indole synthesis, compare Bischler–Möhlau
