Reaction Steps

A mixture of 3-trifluoromethylperfluorobutyl iodide (19.5 g, 50 mmol), p-iodobenzoic acid (12.4 g, 50 mmol), activated copper (15.9 g, 250 mmol) and dried dimethyl sulfoxide (100 ml) is stirred at 130° C. in an autoclave for 14.5 hours. After cooling, the reaction mixture is poured into water (400 ml), and the precipitated solid material is collected by filtration and dried. Then, the solid material is extracted with ethanol (200 ml), and the ethanol extract is concentrated to yield crude p-(3-trifluoromethylperfluorobutyl)benzoic acid (5.8 g). The crude product is recrystallized from ethanol-water. The melting point of the purified product is 189°-190° C.
