Haloform Reaction Mechanism - Explanation, Iodoform Test, …

WebThe reaction mechanism for the haloform test occurs under basic conditions. First, the ketone undergoes a keto-enol tautomerization. Then the nucleophilic enolate attacks the iodine to give an iodine ion and a halogenated ketone. This repeats a total of three times until all hydrogens of the ketone methyl group are replaced by an iodine. Web23 jun. 2024 · Mechanism of action.
