Iodobenzenes are a group of aryl iodides/halobenzenes consisting of one or more iodine atoms as substituents on a benzene core. They have the formula C 6 H 6–n I n, where n = 1–6 is the number of iodine atoms.
Iodobenzene is an aryl iodide and the simplest of the iodobenzenes, consisting of a benzene ring substituted with one iodine atom. Its chemical formula is C 6 H 5 I. It is useful as a synthetic intermediate in organic chemistry. It is a volatile colorless liquid, although aged samples appear yellowish.
This reagent was originally prepared by Conrad Willgerodt [3] by reacting iodobenzene with a mixture of acetic acid and peracetic acid: [4] [5] C 6 H 5 I + CH 3 CO 3 H + CH 3 CO 2 H → C 6 H 5 I(O 2 CCH 3) 2 + H 2 O. PIDA can also be prepared from iodosobenzene and glacial acetic acid: [5] C 6 H 5 IO + 2 CH 3 CO 2 H → C 6 H 5 I(O 2 CCH 3) 2 ...
Thus iodobenzene (C 6 H 5 I) is an iodine(I) compound, (dichloroiodo)benzene (C 6 H 5 ICl 2) and iodosobenzene (C 6 H 5 IO) iodine(III) compounds, and iodoxybenzene (C 6 H 5 IO 2) an iodine(V) compound. With that convention in place, IUPAC names assume complete electron transfer.

The compound can be prepared by reaction of iodobenzene with a mixture of trifluoroperacetic acid and trifluoroacetic acid in a method analogous to the synthesis of (diacetoxyiodo)benzene: [1] It can also be prepared by dissolving diacetoxyiodobenzene (a commercially-available compound) with heating in trifluoroacetic acid: [ 2 ]

Iodosobenzene is prepared from iodobenzene. [3] It is prepared by first oxidizing iodobenzene by peracetic acid. Hydrolysis of resulting diacetate affords "PhIO": [4] C 6 H 5 I + CH 3 CO 3 H + CH 3 CO 2 H → C 6 H 5 I(O 2 CCH 3) 2 + H 2 O C 6 H 5 I(O 2 CCH 3) 2 + H 2 O → C 6 H 5 IO + 2 CH 3 CO 2 H. The structure of iodosobenzene has been ...
