| Abstract：4,4′-Diiodobiphenyl was prepared in 86.21% yield from biphenyl via direct iodination with iodine. The effects of the reactants ratio, the water amount in the reaction medium, the different catalysts and the reaction temperature were investigated. The optimal reaction conditions of the route were as follows: the molar ratio of biphenyl, iodine, and ammonium persulphate was 1:1.1:1.1, the reaction medium was acetic acid and water, the catalyst was concentrated sulfuric acid, the reaction temperature was 85℃. |
| Key words：4,4'-diiodobiphenyl; biphenyl; iodine |
