Iodobenzene reacts readily with magnesium to form the Grignard reagent, phenylmagnesium iodide. Phenylmagnesium iodide, like the bromide analog, is a synthetic equivalent for the phenyl anion synthon. Iodobenzene reacts with chlorine to give the complex, iodobenzene dichloride, [4] which is used as a solid source of chlorine.
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 ...
In 1886, German chemist Conrad Willgerodt prepared the first hypervalent iodine compound, iodobenzene dichloride (Ph I Cl 2), by passing chlorine gas through iodobenzene in a cooled solution of chloroform: [3] Ph I + Cl 2 → PhICl 2. This preparation can be varied to produce iodobenzene pseudohalides.
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 ]

Iodobenzene dichloride is not stable and is not commonly available commercially. It is prepared by passing chlorine gas through a solution of iodobenzene in chloroform, from which it precipitates. [3] The same reaction has been reported at pilot plant scale (20 kg) as well. [4] Ph-I + Cl 2 → PhICl 2
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.
