Iodobenzene is an organoiodine admixture consisting of a benzene ring
commissioned with one iodine atom. It is advantageous as a constructed average
in amoebic chemistry. It is a airy achromatic liquid, although age-old samples
arise yellowish.
Since the C–I tape is weaker than C–Br or C–Cl, iodobenzene is added acknowledging
than bromobenzene or chlorobenzene. Iodobenzene reacts readily with magnesium
to anatomy the Grignard reagent, phenylmagnesium iodide. Phenylmagnesium
iodide, like the boiler analog, is a constructed agnate for the phenyl anion
synthon. Iodobenzene reacts with chlorine to accord the complex, iodobenzene
dichloride, which is acclimated as a solid antecedent of chlorine.
Iodobenzene can aswell serve as a substrate for the Sonogashira coupling,
Heck reaction, and added metal-catalyzed couplings. These reactions advance via
the oxidative accession of iodobenzene.
