Versuchsvorschrift

7.82 g (100 mmol) of benzene, 8.52 g (20 mmol) of 5-iodooctafluoro-3-oxapentanesulfonyl fluoride, 4.84 g (20 mmol) of benzoyl peroxide, 0.36 g (2 mmol) of copper (II) acetate, and 100 mL of acetic acid were refluxed for 4 hrs at 115° C. Then the mixture was stirred at room temperature overnight. The mixture was diluted with water (˜100 mL), and the product was extracted with hexane and washed with water until neutral pH was obtained. The solvent was removed to yield dark yellow oil. The product was purified by distillation under reduced pressure (˜27 inch Hg). The first faction was composed of a mixture of the product plus iodobenzene (2.8 g, approximately 1:1 ratio). The second fraction consisted of 2.1 g of pure product (colorless oil) (28% yield).
