suzuki reaction | [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. [Beilstein 5 IV 700.] | [References]
