Synthesis of 1-iodo-2-nitrobenzene

Preparation of 1-iodo-2-nitrobenzene

Preparation of 1-iodo-2-nitrobenzene

Preparation of 1-iodo-2-nitrobenzene

Water (1000 ml) is poured over 0-nitroaniline (100 g), then concentrated sulfuric acid (600g) is added; the resulting clear solution is cooled to 5° C and diazotized with the appropriate amount of sodium nitrite, during which the temperature should not rise above 10° C. The diazonium salt solution is added in portions to a solution of potassium iodide (200 g) and iodine (200 g) in water (200 ml). When evolution of nitrogen ceases, the mixture is warmed for some time on a water bath and shaken while still warm with sulfite solution; on cooling, o-iodonitrobenzene, m.p. 54° C, crystallizes in quantitative yield.
