Reaction Steps

A 100 ml Schlenk flask equipped with a stir bar was flame-dried and then charged with 1,4-diiodobenzene (3.30 g, 10 mmol), Cu powder (5.08 g, 80 mmol), and 2,2′-bipy (156 mg, 1 mmol). The flask was evacuated and back-filled with argon three times. Anhydrous dimethylsulfoxide (30 mL) was added via a syringe. Perfluorohexyl iodide (6.5 mL, 30 mmol) was added dropwise while stirring. Upon completion of addition, the reaction mixture was heated to 70° C. for 72 hours then removed from heat. The reaction mixture was poured into 100 mL H2O/100 mL diethyl ether and stirred vigorously for 30 min. Solid residues were removed by filtration, and the organic layer was washed twice with dilute NH4OH solution, twice with water, dried over MgSO4. The solvent was removed by evaporation under reduced pressure, and the resulting off-white solids were subjected to sublimation to give S5 as white solids (5.61 g, 78%). 1H NMR (300 MHz, CDCl3): δ 7.77 (s, 4H). 19F NMR (282 MHz, CDCl3): δ −126.58 (4F), −123.26 (4F), −122.15 (4F), −121.87 (4F), −111.71 (4F), −81.16 (6F).
