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.

The iodobenzene diacetate product hydrolyzes to the polymeric iodosobenzene (PhIO), which is stable in cool alkaline solution. [6] In hot water (or, in Willgerodt's original preparation, steam distillation), iodosobenzene instead disproportionates to iodoxybenzene and iodobenzene: [7] 2 PhIO → PhIO 2 + PhI

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 ]
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.

Under protic conditions, ketones undergo α-hydroxylation and dimethyl acetal formation. Both iodosylbenzene and iodobenzene diacetate (IBD) can effect this transformation. This method can be used to synthesize α-hydroxy ketones after acidic hydrolysis of the ketal functionality. [1
