Term Name: secondary alpha-hydroxy ketone
Synonyms: acyloin, acyloins, secondary alpha-hydroxy ketones, secondary alpha-hydroxy-ketone, secondary alpha-hydroxy-ketones, secondary alpha-hydroxyketone, secondary alpha-hydroxyketones
Definition: An alpha-hydroxy ketone in which the carbonyl group and the hydroxy group are linked by a carbon bearing one hydrogen and one organyl group. Secondary alpha-hydroxy ketones are also known as acyloins, and are formally derived from reductive coupling of two carboxylic acid groups.
