, p. 2289 - 2292 (2004)
4,4′-Bis(dichloroiodo)biphenyl and 3-(dichloroiodo)benzoic acid are convenient recyclable hypervalent iodine reagents for vicinal chloromethoxylation or iodomethoxylation of unsaturated compounds. The reactivity of these reagents in the reaction of vicinal halomethoxylation is generally similar to dichloroiodobenzene and the advantage of their use is that the reduced forms of these reagents can be easily separated from the reaction mixture and reused for the regeneration of the reagents.

Regioselective vicinal functionalization of unactivated alkenes with sulfonium iodate(i) reagents under metal-free conditions

, p. 7529 - 7543 (2016/08/16)
Metal-free, molecular iodine-free direct 1,2-difunctionalization of unactivated alkenes has been reported. The sulfonium iodate(i) reagent efficiently promoted the intermolecular vicinal iodo-functionalization of a diverse range of olefins in a stereo and regioselective manner. This method enables the divergent and straightforward preparation of synthetically useful functionalities; β-iodocarboxylates, β-iodohydrins, and β-iodoethers in a one-step process. Further interconversion of iodo-functionalized derivatives allows easy access to valuable synthetic intermediates en route to biologically active molecules.
Benzyl(triphenyl)phosphonium Dichloroiodate: A New Reagent for Coiodination of Alkenes
Alikarami, Mohammad,Farhadi, Mansoureh
, p. 1302 - 1306 (2015/09/22)
A mild, efficient, and regio- and stereoselective method for iodoalkoxylation and iodohydroxylation of olefins has been developed using benzyl(triphenyl)phosphonium dichloroiodate as iodine source. This procedure led to the corresponding iodoalkoxylated and iodohydroxylated products in moderate to excellent yields.

The present invention provides new stable crystalline N-iodoamides - 1-iodo- 3,5,5-trimethylhydantoin (1-ITMH) and 3-iodo-4,4-dimethyl-2-oxazolidinone (IDMO). The present invention further provides a process for the preparation of organic iodides using N-iodoamides of this invention and recovery of the amide co-products from waste water.
Dichloroiodoisocyanuric acid: A new reagent for regioselective coiodination of alkenes and iodination of activated arenes
Da Silva Ribeiro, Rodrigo,Esteves, Pierre M.,De Mattos, Marcio C.S.
experimental part, p. 228 - 235 (2012/05/05)
Dichloroiodoisocyanuric acid was prepared in 93% by heating trichloroisocyanuric acid with 1.05 mol equiv. of iodine. This new reagent is very efficient for regioselective electrophilic iodination of activated arenes. Alkenes react with dichloroiodoisocyanuric acid in the presence of oxygenated nucleophiles (water, alcohols, and acetic acid), leading to the corresponding iodohydrins, β-iodoethers and β-iodoacetates with reaction times of less than one minute and with a high degree of regioselectivity. Enol ethers resulted in the regioselective formation of the corresponding iodine-dialkylacetals. Experimental results and DFT calculations showed that dichoroiodoisocyanuric acid is more reactive with unsaturated systems than triiodoisocyanuric acid.
Comparative study of the vicinal functionalization of olefins with 2:1 bromide/bromate and iodide/iodate reagents
Agrawal, Manoj K.,Adimurthy, Subbarayappa,Ganguly, Bishwajit,Ghosh, Pushpito K.
experimental part, p. 2791 - 2797 (2009/08/08)
A comparative evaluation was made on the syntheses of vicinal halohydrins, halo methyl ethers, and halo acetates from olefins using 2:1 Br-/BrO3- and I-/IO3- reagents. In many cases both reagents afforded products selectively in high yields. The highest halogen atom efficiencies attained were 97% and 93% for Br-/BrO3- and I-/IO3-, respectively. Of the two reagents, I-/IO3- was established to be the preferred reagent for vicinal functionalization of linear alkenes and also for halo acetate preparation. However, only Br-/BrO3- was effective for vicinal functionalization of trans-stilbene and chalcones.

Yusubov, Mekhman S.,Yusubova, Roza Ya.,Kirschning, Andreas,Park, Joo Yeon,Chi, Ki-Whan
, p. 1506 - 1509 (2008/09/19)
An efficient and facile method for the iodo-functionalization of alkenes 5 and alkynes 6 by using recyclable m-iodosylbenzoic acid (2) was developed. The final products can be easily isolated without any chromatographic purification by simple treatment of the crude mixture with an anionic exchange resin. Unreacted m-iodosylbenzoic acid and reduced m-iodobenzoic acid are effectively recovered from the resin by acidification with hydrochloric acid.
Triiodoisocyanuric acid: a new and convenient reagent for regioselective coiodination of alkenes and enolethers with oxygenated nucleophiles
Ribeiro, Rodrigo da S.,Esteves, Pierre M.,de Mattos, Marcio C.S.
, p. 8747 - 8751 (2008/03/18)
The reaction of triiodoisocyanuric acid (prepared from I2 and trichloroisocyanuric acid in 90% yield) with alkenes in the presence of oxygenated nucleophilic solvents (alcohols, AcOH and H2O) led to the corresponding β-iodoethers, β-iodoacetates and iodohydrins, in 66-98% isolated yield. Enolethers reacted with triiodoisocyanuric acid in MeOH to produce dialkylacetals (70-83%).
RETRACTED ARTICLE: Regioselective 1,2-hydroxy and methoxy iodination of alkenes by molecular iodine and aqueous hydrogen peroxide
Raju, B. Rama,Kumar, E.K. Pramod,Saikia, Anil K.
, p. 1997 - 2001 (2007/10/03)
Treatment of an alkene with iodine and aqueous hydrogen peroxide (30%) in acetonitrile gives the corresponding hydroxyiodoalkane regioselectively in high yield. On the other hand the same reaction in methanol gives methoxyiodoalkanes in excellent yield.
