A simple, efficient, mild, and regioselective method for oxyiodination of carbonyl compounds has been reported by using NH4I as the source of iodine and Oxone® as an oxidant. Various carbonyl compounds such as aralkyl ketones, aliphatic ketones (acyclic and cyclic), and β-keto esters proceeded to the respective α-monoiodinated products in moderate to excellent yields. Unsymmetrical aliphatic ketones
The reaction of aromatic acetyl derivatives with potassium iodide and potassium iodate in acetic acid in the presence of sulfuric acid at room temperature gave iodoacethyl derivatives in good yields.
