1-Bromo-4-iodobenzene synthesis

14synthesis methods
The p-bromoiodobenzene was synthesized by diazotization and iodination using industrial p-bromoaniline as raw material. The better synthesis conditions: firstly, 0.02 mol of p-bromoaniline was dissolved in 20% sulfuric acid, and reacted with 0.021 mol of
-

Yield:589-87-7 99%

Reaction Conditions:

with potassium iodide in water at 25; for 0.0833333 h;Sandmeyer Reaction;Solvent;

Steps:

3.2. General Procedure for Synthesis of Aryl Iodides (2)from Aryl Diazofluoroborates

General procedure: To a suspension of aryl diazofluoroborate (1 mmol) inwater (3mL), aqueous solution of potassium iodide (1.5 mmol in 2mL H2O) was added in single lot at room temperature.Reaction mixture was stirred for specific time (Table 2).The solid product was separated by filtration and the liquidproducts were separated by extraction in diethyl ether (5mL).The organic layer was dried over anhydrous Na2SO4 andsolvent was removed at room temperature afforded pure iodocompounds in excellent yields. Further all synthesized compoundswere characterized and confirmed by comparisonwith reported aryl iodides.
