Iodination of industrially important aromatic compounds with aqueous potassium triiodide
Sharma,Srivastava,Agarwal,Diwedi
, p. 433 - 436 (2016/06/13)
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.

A green reagent for the iodination of phenols
Kiran,Konakahara, Takeo,Sakai, Norio
experimental part, p. 2327 - 2332 (2009/04/04)
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.

Reddy, K. Suresh Kumar,Narender,Rohitha,Kulkarni
experimental part, p. 3894 - 3902 (2009/04/04)
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.

Nitrophenol derivatives oxidized by cerium(IV) ammonium nitrate (CAN) and their cytotoxicity
Pan, Wen-Bin,Wei, Li-Mei,Wei, Li-Lan,Wu, Chin-Chung,Chang, Fang-Rong,Wu, Yang-Chang
, p. 581 - 588 (2007/10/03)
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.
Eco-friendly oxidative iodination of various arenes with sodium percarbonate as the oxidant http://www.mdpi.org
Zielinska, Agnieszka,Skulski, Lech
, p. 1307 - 1317 (2007/10/03)
Six easy laboratory procedures are presented for the oxidative iodination of various aromatics, mostly arenes, with either molecular iodine or potassium iodide (used as the sources of iodinating species, I+ or I 3+), in the presence of sodium percarbonate (SPC), a stable, cheap, easy to handle, and eco-friendly commercial oxidant.
Three-dimensional aggregation in 2-hydroxy-3-iodo-5-nitrobenzaldehyde involving C - H...O, iodo-nitro and aromatic π-π stacking interactions, and isolated dimers in disordered 2,4-diiodo-6-nitroanisole
Garden, Simon J.,Da Cunha, Fernando R.,Glidewell, Christopher,Low, John N.,Skakle, Janet M.S.,Wardell, James L.
, p. o12-o14 (2007/10/03)
The molecular and supramolecular structures of 2-hydroxy-3-iodo-5-nitrobenzaldehyde (I) and 2,4-diiodo-6-nitroanisole (II) were analyzed. The crystallographic atom numbering scheme differed from the conventional chemical numbering scheme in order that bot

Krishna Mohan,Narender,Kulkarni
, p. 8015 - 8018 (2007/10/03)
Oxyiodination of aromatic compounds using NH4I and Oxone gives high yields and selectivity. A simple method for the iodination of aromatic compounds using NH4I as the iodine source and Oxone as the oxidant is described.
Influence de la complexation sur la reactivite de nitrates d'halogenes
Gaude, Didier,Gellon, Gisele,Goaller, Raymond Le,Pierre, Jean-Louis
, p. 104 - 108 (2007/10/02)
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.

Kajigaeshi, Shoji,Kakinami, Takaaki,Yamasaki, Hiromichi,Fujisaki, Shizuo,Kondo, Manabu,Okamoto, Tsuyoshi
, p. 2109 - 2112 (2007/10/02)
The reaction of phenols with benzyltrimethylammonium dichloroiodate(1-) in dichloromethane-methanol in the presence of CaCO3 or NaHCO3 for several hours at room temperature gave iodophenols in good yields.
