Procedure

To a mixture of 19 g phosphoric acid (98%) and 19 g potassium iodide are added at 40° under stirring 4.75 g (33.4 mMol) of 4,4,4-trifluoro-3-methyl-butan-1-ol over a period of 10 minutes. The mixture is then heated at 120° for 16 hours, a cooling poured into ice-water and extracted with diethylether. The etheric extracts are washedwith 10% sodium thiosulfate and brine acid dried over sodium sulphate. After filtration, the solvent is removed through a 15 cm Vigreux-column atatmospheric pressure, followed by fractionation giving 4,4,4-trifluoro-3-methyl-1-iodo-butane, b.p. 76°-77° at 140 mbar.
