CHEM 2325 Module 27: Haloform Reaction; Mechanism of Base-catalyzed Alpha Halogenation

When a methyl ketone is exposed to Iₒ under basic conditions, a carboxylate salt and iodoform are obtained. The product of alpha halogenation cannot be isolated under these reaction conditions. The mechanism of the haloform reaction, which also describes the mechanism of base-catalyzed alpha halogenation, is outlined.
