Iodination of aromatic compounds using potassium iodide and hydrogen peroxide
Reddy, K. Suresh Kumar,Narender,Rohitha,Kulkarni
, p. 3894 - 3902 (2008)
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.

Ecofriendly iodination of activated aromatics and coumarins using potassium iodide and ammonium peroxodisulfate
Ganguly, Nemai C.,Barik, Sujoy Kumar,Dutta, Sanjoy
, p. 1467 - 1472 (2010)
An environmentally benign protocol for the iodination of activated aromatics, such as phenols, anilines, and hydroxycou-marins, using inexpensive commercially available potassium iodide and ammonium peroxodisulfate (1:2.5 molar equivalents per mole of substrate) in aqueous methanol (MeOH-H 2O, 6:1) at room temperature has been developed. The protocol provides for ortho-selective monoiodination as the predominant product without added acid and it is compatible with a number of common oxidizible functional groups, such as formyl, benzylic C-H, aromatic amines and hydroxymethyl. Good to acceptable yields of monoiodinated products in acceptable reaction times and exclusive ortho-iodination for 7-hydroxycoumarins, despite the presence of vinylogous electronrich C3, are some of the key advantageous features of the method.

Gas-Chromatographic identifi cation of products formed in iodination of methyl phenols by retention indices

Iodination reaction followed by conversion of iodine-substituted methylphenols to the corresponding trifl uoroacetates was suggested for improving the sensitivity of the gas-chromatographic determination of phenol and its methyl-substituted derivatives (al isomers of mono- and diethylphenols, 2,3,5-, 2,3,6-, and 3,4,5-trimethylphenols) in aqueous media. Acylation products of iodo methylphenols (104 compounds) were identifi ed by linear-logarithmic retention indices on a standard nonpolar polydimethylsiloxane stationary phase, and the pattern of their variation with the number and nature of substituents were characterized. A procedure for identifi cation of methyl-substituted phenols in water in their gas-chromatographic determination with an electron-capture detector was developed. Pleiades Publishing, Ltd., 2012.
Iodination of anilines and phenols with 18-crown-6 supported ICl 2-
Mbatia, Hannah W.,Ulloa, Olbelina A.,Kennedy, Daniel P.,Incarvito, Christopher D.,Burdette, Shawn C.
experimental part, p. 2987 - 2991 (2011/06/16)
A highly crystalline iodinating reagent, {[K·18-C-6]ICl 2}n, was synthesized in high yield (93%). The trihalide is supported by an 18-crown-6 macrocycle and forms a coordination polymer in the solid state. This reagent iodinates anilines and phenols efficiently under mild conditions. Controlled mono-iodination with anilines was easily achieved while poly-iodination was observed with phenols.
