www.siue.eduAldol Condensation An aldehyde or ketone that has a hydrogen next to the carbonyl group, an a-hydrogen, can form an enolate in basic solution, and the enolate can react by nucleophilic addition at the carbonyl group of another molecule. This process is a very important synthetic procedure and is known as the Aldol Condensation.
