| | 1,4-Diiodobenzene Usage And Synthesis |
| Chemical Properties | 1,4-Diiodobenzene appears as white to light orange crystals or powder. Its melting point is 131–132 °C, and it boils at 285 °C (sublimes). The compound is readily soluble in ether and ethanol, but insoluble in water. | | Uses | 1,4-Diiodobenzene is used in Suzuki reaction. It is used as a precursor in the preparation of martinellic acid and 1,4-bis(p-R-phenylethynyl)benzenes. Further, it is employed in the preparation of 1,4-diiodo-2,5-didodecylbenzene , which is a starting reagent for the synthesis of oligo(1,4-phenylene ethynylene). It is also used in human and animal nutrition products including antiseptics and disinfectants. In addition to this, it used in polarizing films for liquid crystal display chemicals. | | Preparation | 1,4-Diiodobenzene is obtained by diazotising p-iodoaniline followed by substitution. An alternative preparation method involves diazotising p-phenylenediamine hydrochloride, followed by substitution with potassium iodide. | | Purification Methods | Crystallise it from EtOH or boiling MeOH, then dry it in air.
