A novel approach to the preparation of imidazole-substituted cyclic iodonium salts has been developed via the oxidative cyclization of 1-phenyl-5-iodoimidazole using a cheap and available Oxone/H2SO4 oxidative system. The structure of the new polycyclic heteroarenes has been confirmed by single-crystal X-ray diffractometry, revealing the characteristic structure features for cyclic iodonium salts. The newly produced imidazole-flanked cyclic iodonium compounds were found to readily engage in a heterocyclization reaction with elemental sulfur, affording benzo[5,1-b]imidazothiazoles in good yields.
An Investigation of (Diacetoxyiodo)arenes as Precursors for Preparing No-Carrier-Added [18F]Fluoroarenes from Cyclotron-Produced [18F]Fluoride Ion

Treatment of (diacetoxyiodo)arenes (1a-1u) with cyclotron-produced [18F]fluoride ion rapidly affords no-carrier-added [18F]fluoroarenes (2a-2u) in useful yields and constitutes a new method for converting substituted iodoarenes into substituted [18F]fluoroarenes in just two steps.
A mild carbon-boron bond formation from diaryliodonium salts
Miralles,Romero,Fernández,Mu?iz
supporting information, p. 14068 - 14071 (2015/09/15)
The direct metal-free borylation of diaryliodonium salts with diboron reagents is now demonstrated to be a feasible process toward formation of aryl boronic esters without any additive or catalysts, and it can be extended to a two-step C-C coupling of both aryl groups of the initial diaryliodonium reagent.
Direct arylation of benzoxazole C-H bonds with iodobenzene diacetates
Yu, Peng,Zhang, Guangyou,Chen, Fan,Cheng, Jiang
supporting information; experimental part, p. 4588 - 4590 (2012/09/22)
A Pd (OAc)2-catalyzed direct arylation of benzoxazole C-H bonds has been achieved with iodobenzene diacetates as the arylation reagent in moderate to good yields. The procedure tolerates a series of functional groups, such as methoxy, nitro, cyano, chloro, and bromo groups.
Rapid and efficient radiosyntheses of meta-substituted [ 18F]fluoroarenes from [18F]fluoride ion and diaryliodonium tosylates within a microreactor
Chun, Joong-Hyun,Lu, Shuiyu,Pike, Victor W.
experimental part, p. 4439 - 4447 (2011/10/08)
Effective methods for the introduction of the short-lived positron-emitter fluorine-18 (t1/2 = 109.7 min) at high specific radioactivity into fluoroarenes are valuable for the development of radiotracers for molecular imaging with positron emis

Easy preparation of (diacetoxyiodo)arenes from iodoarenes with sodium percarbonate as the oxidant
Zielinska, Agnieszka,Skulski, Lech
, p. 806 - 809 (2007/10/03)
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
Kazmierczak, Pawel,Skulski, Lech,Kraszkiewicz, Lukasz
, p. 881 - 891 (2007/10/03)
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.
Synthesis of functionalised unsymmetrical diaryliodonium salts
Shah, Aneela,Pike, Victor W.,Widdowson, David A.
, p. 2463 - 2465 (2007/10/03)
A generalised synthesis of unsymmetrical functionalised diaryliodonium salts has been developed through the direct reaction of bis(acetoxy)iodoarenes with arenes in a trifluoromethanesulfonic or trifluoroacetic acid medium.
