The iodination of aromatic compounds (polymethylbenzenes, alkyl phenyl ethers, and polynuclear aromatic hydrocarbons) with iodine in combination with copper(II) chloride or sulfate supported on alumina proceeds well under mild conditions to selectively gi

An electrochemical access to iodinated aromatic compounds starting from trimethylsilyl-substituted arenes is presented. By design of experiments, highly efficient and mild conditions were identified for a wide range of substrates. A functional group stability test and the synthesis of an important 3-iodobenzylguanidine radiotracer illustrate the scope of this process.

The cobalt-catalyzed Diels-Alder reaction of trimethylsilyl-substituted alkynes with 1,3-dienes led to dihydroaromatic intermediates which were transformed into iodobenzene derivatives. For this transformation, the dihydroaromatic intermediates had to be oxidized and the trimethylsilyl-substituted arene had to undergo a silicon-iodine exchange reaction. For this purpose, a number of oxidizing agents and iodonium sources were tested in order to realize the desired two transformations in a single step. Eventually, the combination of tert-butyl hydroperoxide (TBHP), zinc iodide, and potassium carbonate led to the desired oxidation/iodination in good to excellent yields in a short reaction time at ambient temperatures.
An in situ acidic carbon dioxide/glycol system for aerobic oxidative iodination of electron-rich aromatics catalyzed by Fe(NO3)3·9H2O

, p. 4308 - 4312 (2015/01/08)
An environmentally benign CO2/glycol reversible acidic system was developed for the iron(iii)-catalyzed aerobic oxidative iodination of electron-rich aromatics without the need for any conventional acid additive or organic solvent. Notably, moderate to high isolated yields (up to 97%) of the aryl iodides were attained with comparable regioselectivity when ferric nitrate nonahydrate was used as the catalyst with molecular iodine under 1 MPa of CO2.
Simple and regioselective oxyiodination of aromatic compounds with ammonium iodide and Oxone
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.
Selective and effective iodination of alkyl-substituted benzenes with elemental iodine activated by Selectfluor F-TEDA-BF4
Stavber, Stojan,Kralj, Petra,Zupan, Marko
, p. 598 - 600 (2007/10/03)
Selective direct introduction of an iodine atom into alkyl-substituted benzene derivatives was effectively achieved by reaction of target molecules with elemental iodine in the presence of 1-chloromethyl-4-fluoro- 1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (Selectfluor F-TEDA-BF4). The number of iodine atoms introduced could be modulated by the molar ratio between substrate, iodine and F-TEDA-BF4.
Halogenation Using Quaternary Ammonium Polyhalides. XIV. Aromatic Bromination and Iodination of Arenes by Use of Benzyltrimethylammonium Polyhalides-Zinc Chloride System
Kajigaeshi, Shoji,Kakinami, Takaaki,Moriwaki, Masayuki,Tanaka, Toshio,Fujisaki, Shizuo,Okamoto, Tsuyoshi
, p. 439 - 443 (2007/10/02)
The reaction of arenes with benzyltrimethylammonium tribromide or benzyltrimethylammonium dichloroiodate in acetic acid in the presence of ZnCl2 at room temperature or at 70 deg C gave brome- or iodo-substituted arenes in good yield, respectively.
