Iodobenzene is widely used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds. It serves as a key intermediate in the production of pharmaceuticals, agrochemicals, and fine chemicals. In palladium-catalyzed cross-coupling reactions, such as the Suzuki and Heck reactions, iodobenzene acts as an arylating agent, enabling the introduction of phenyl groups into target molecules. It is also employed in the synthesis of organometallic compounds and as a precursor in the preparation of other iodinated aromatic compounds. Additionally, iodobenzene finds use in research laboratories for studying reaction mechanisms and developing new synthetic methodologies. Its stability and reactivity make it a valuable tool in various chemical transformations.
