Iodobenzene
Iodobenzene (CAS: 591-50-4), with the molecular formula C6H5I and a molar mass of 204.01 g/mol, is a clear, brown to yellow liquid possessing a benzene-like odour. It is miscible with alcohol and insoluble in water. This halogenated hydrocarbon serves as a valuable building block in organic synthesis, particularly in the formation of carbon-carbon and carbon-heteroatom bonds. Its applications span various chemical synthesis pathways.

Organic Synthesis Building Block
Iodobenzene is a key aryl halide utilised in cross-coupling reactions such as Suzuki, Heck, and Sonogashira couplings. These reactions are fundamental for constructing complex organic molecules and are widely employed in the pharmaceutical and materials science industries.
Precursor for Organometallic Reagents
It can be used to generate organometallic compounds, like phenylmagnesium iodide (a Grignard reagent) or phenylithium, which are versatile intermediates in synthetic chemistry for nucleophilic addition reactions.
Ligand Synthesis
Iodobenzene can serve as a starting material in the synthesis of various ligands, particularly phosphine ligands, which are crucial in homogeneous catalysis.
