A Solution of bromobenzene (488 mg, 3.1 mmol) in anhydrous THF (10 mL) under nitrogen was cooled to -78 °C. Then butyllithium (ca. 1.6mol/L in hexane, 1.9 mL, 3.1 mmol) was added dropwise and stirred at the same temperature for 30 min. To this, octafluorocyclopentene (300 mg, 1.4 mmol) was added and stirred at -78 °C for 1 h. The reaction mixture was quenched with water and extracted with diethyl ether. The organic layer was dried over anhydrous sodium sulfate and filtered. The solvent was removed under reduced pressure and the residue was purified by column chromatography (on silica gel, hexane) to give 1 as a white solid (414 mg, 89% yield).
The reaction mixture was monitored by TLC (hexane, Rf = 0.45).
1,2-Diphenyl-3,3,4,4,5,5-hexafluorocyclopentene (1)
1H NMR (270 MHz, CDCl3); δ 7.43-7.29 (m, 10H)
