As you will see, these reactions proceed through the formation of the enol form of the carbonyl compound. After a brief review of keto-enol tautomerism, we begin our discussion of alpha-substitution reactions by looking at the methods used to introduce a halogen atom into a carbonyl-containing compound—reactions.
