- Oxidative Iodination of Aromatic Amides Using Sodium Perborate or Hydrogen Peroxide with Sodium Tungstate
-
Hydrogen peroxide or sodium perborate in the presence of a sodium tungstate catalyst are shown to be cheap oxidants for the iodination of aromatic amides using potassium iodide as the source of the iodine.

- A para-C–H Functionalization of Aniline Derivatives via In situ Generated Bulky Hypervalent Iodinium Reagents
-
A practical para-C-H functionalization of aniline derivatives has been developed using an in situ generated bulky hypervalent iodinium reagent. Para-iodo, bromo, chloro, nitro, trifluormethyl aniline derivatives can be obtained efficiently, in many cases in 10 min in a transition metal-free manner. Medicinal chemicals or intermediates can be purified without column chromatography or recrystallization, which significantly reduces the waste and simplifies the work-up process.

- Halogenation Using Quaternary Ammonium Polyhalides. XVII. Iodination of Acetanilide Derivatives with Benzyltrimethylammonium Dichloroiodate and Zinc Chloride
-
The reaction of acetanilide derivatives with benzyltrimethylammonium dichloroiodate in acetic acid in the presence of ZnCl2 at room temperature or at 70 deg C gave iodo-substituted acetanilide derivatives in good yields.
