Reaction Steps

An acetonitrile solution (20 ml) of 3-pentafluoroethyl-1H-pyrazole (2.0 g), dicerium ammonium nitrate (3.0 g) and iodine (1.6 g) was refluxed for 3 hours. After cooling, the reaction solution was washed with saturated aqueous solution of sodium thiosulfate and saturated aqueous solution of sodium chloride. After drying the organic layer with magnesium sulfate, the solvent was distilled off under the reduced pressure to obtain 4-iodo-3-pentafluoroethyl-1H-pyrazole (3.2 g).
