- AuIII-Catalyzed Formation of α-Halomethyl Ketones from Terminal Alkynes
-
A AuIII-catalyzed synthesis of α-halomethyl ketones from terminal alkynes was developed. This approach features excellent functional group compatibility and good yields for both aromatic and aliphatic terminal alkynes. The resulting α-halomethyl ketones were used to prepare heterocyclic indolizine structures. The plausible mechanism of the one-pot reaction is proposed.

- Oxidative iodination of carbonyl compounds using ammonium iodide and oxone
-
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 reacted smoothly yielding a mixture of 1-iodo and 3-iodo ketones with the predominant formation of 1-iodoproduct.

- Preparation of Aromatic Iodoacetyl Derivatives by Direct Iodination with a Potassium Iodide-Potassium Iodate-Sulfuric Acid System
-
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 iodoacetyl derivatives in good yields.
