Mild and efficient synthesis of iodylarenes using Oxone as oxidant

Mild and efficient method for the preparation of iodylarenes by oxidation of iodoarenes with Oxone in aqueous acetonitrile at room temperature is described. This new procedure allows the preparation of various iodylarenes with electron-donating or electron-withdrawing substituents in the aromatic ring including the previously unknown 1,2-diiodylbenzene.

NUCLEOPHILIC FLUORINATION OF AROMATIC COMPOUNDS

Iodylbenzene derivatives substituted with electron donating as well as electron withdrawing groups on the aromatic ring are used as precursors in aromatic nucleophilic substitution reactions. The iodyl group (IO2) is regiospecifically substituted by nucleophilic fluoride to provide the corresponding fluoroaryl derivatives. No-carrier-added [F-18] fluoride ion derived from anhydrous [F- 18]KF/Kryptofix, [F-18]CsF or a quaternary ammonium fluoride (e.g., Me4NF, Et4NF, n-Bu4NF, (PhCH2)4NF) exclusively substitutes the iodyl moiety in these derivatives and provides high specific activity F- 18 labeled fluoroaryl analogs. Iodyl derivatives of a benzothiazole analog and 6-iodyl-L-dopa derivatives have been synthesized as precursors and have been used in the preparation of no-carrier-added [F-18]fluorobenzothiazole as well as 6-[F-18]fluoro-L-dopa.

Transition metal-mediated oxidations utilizing monomeric iodosyl- and iodylarene species

Several transition metal-mediated oxidations using hypervalent iodine species are reported. A convenient procedure for preparation of iodylarenes via RuCl3-catalyzed oxidation of iodoarenes has been developed. This procedure allows the generation of highly reactive monomeric iodine(V) species, which are excellent oxidants toward alcohols and hydrocarbons in situ. A broad range of substrates can be oxidized to carbonyl compounds by a tandem catalytic system based on the Ru(III)-catalyzed reoxidation of ArIO to ArIO2 using Oxone as oxidant. It was shown that electrophilic iodine(III) species, originating from oligomeric iodosylbenzene sulfate (PhIO)3SO3, are efficient oxygenating agents in catalytic oxidation of aromatic hydrocarbons in the presence of metalloporphyrin complexes.

RuCl3-catalyzed oxidation of iodoarenes with peracetic acid: New facile preparation of iodylarenes

New facile methodology for the preparation of pentavalent iodine compounds using peracetic acid as an oxidant in the presence of catalytic amounts of ruthenium trichloride is described. The new procedure allows the preparation of several previously unknown iodylarenes bearing strongly electron-withdrawing CF3 groups in the aromatic ring.

Easy preparation of (diacetoxyiodo)arenes from iodoarenes with sodium percarbonate as the oxidant

Easy and effective preparations of nearly pure (diacetoxyiodo)arenes, ArI(OAc)2, from iodoarenes, ArI, are reported. In most cases the crude colorless products thus obtained need not be further purified, i.e., by recrystallization. As an example, the PhI(OAc)2 thus prepared was 99% pure (by iodometry).

Syntheses of (diacetoxyiodo)arenes or iodylarenes from iodoarenes, with sodium periodate as the oxidant

Easy, safe, and effective novel methods for preparing either (diacetoxyiodo)-(arenes, ArI(OAc)2, or iodylarenes, ArIO2, from the corresponding iodoarenes, ArI, using sodium periodate as the oxidant are presented in this paper. In order to obtain 2- and 4-iodylbenzoic acids, the respective sodium salts of 2- and 4-iodobenzoic acids should be used as the starting substrates, because mixtures containing the corresponding iodosyl derivatives as the main products along with the intended iodyl compounds are produced from the free parent acids.

Simple anf Efficient Palladium-Catalyzed Carbonylation of Iodoxyarenes in Water under Mild Conditions

Iodoxyarenes (ArIO2) readily react with CO (1 atm) in water, in the presence of Na2 (0.1percent) and Na2CO3 at 40-50 deg C, to give the corresponding carboxylic acids, ArCOOH, in 55-89percent isolated yield.Particulary attractive features of the reaction are that, unlike most iodoarenes, ArIO2 can be carbonylated in aqueous media without any organic solvents, due to their solubility in water and high reactivity.
