- Iodination of industrially important aromatic compounds with aqueous potassium triiodide
-
A new reagent system consisting of aqueous KI3in AcOH and NaIO4as oxidant has been found to be effective in iodinating a variety of commercially important aromatic substrates under ambient conditions. The presence of Na2SO3enhances the yield and the product purity. The procedure ensures high yields (72–98%) at room temperature in a short reaction time. A remarkable feature of this system is that even acidsensitive functionalities like anilines can be iodinated quantitatively.

- Iodination of aromatic compounds using potassium iodide and hydrogen peroxide
-
A simple, efficient, regioselective, and ecofriendly method for oxyiodination of aromatic compounds is presented. In this method, the electrophilic substitutions of iodine generated in situ from KI as an iodine source and hydrogen peroxide as an oxygen source have been employed without any catalyst/mineral acid for the first time.

- A green reagent for the iodination of phenols
-
A new reagent (I2/NaNO2) for the iodination of the aromatic ring of phenols has been discovered. The reaction proceeds at room temperature in 1.5-6 hours. In the presence of this reagent, iodinated compounds are regioselectively formed in significant yields from the corresponding substrates. Georg Thieme Verlag Stuttgart.

- Nitrophenol derivatives oxidized by cerium(IV) ammonium nitrate (CAN) and their cytotoxicity
-
Oxidation of a series of phenols with cerium(IV) ammonium nitrate (CAN) in acetonitrile undermild conditions yields the mixture of corresponding nitrophenols. In the cases of methylphenols and hydroxy-carboxylic acids, the steric effect may reduce the nitration reaction. Compounds 3 a and 4b showed selective activities to Hep 3B and Hep G2 cancer cell lines, respectively. Compound 2c showed selective activities to Hep G2 and MDA-MB-231 cancer cell lines. Further more, com pound 10b showed selective activities to Hep G2, Hep 3B, MCF-7 and MDA-MB-231 cancer cell lines.

- Influence de la complexation sur la reactivite de nitrates d'halogenes
-
Iodine nitrate or bromine nitrate in acetonitrile or in chloroform react with a variety of phenolic substrates to form both halogenated and nitrated products.In the presence of strong complexing agents of halonium ions, no reacting occurs, while in the presence of pyridine or triethylamine, only halogenated phenols exhibiting a strong ortho-directing effect of the phenolic function are produced. Keywords: phenols, iodine nitrate, bromine nitrate, halogenation, nitration.
