Versuchsvorschrift

To a stirred solution of 2-((4-vinylnaphthalen-1-yl)methyl)isoindoline-1,3-dione (1.5 g, 4.79 mmol) in 1,2-dichlorobenzene (15 mL) were added 1-(1-bromo-2,2,2-trifluoroethyl)-3,4,5-trichlorobenzene (3.2 g, 9.5 mmol), CuCl (24 mg, 0.24 mmol) and 2,2-bipyridyl (0.149 g, 0.95 mmol), and the resultant reaction mixture was degassed with argon for 30 min and then stirred at 180° C. for 14 h. After the reaction was deemed complete by TLC, the reaction mixture was cooled to ambient temperature and filtered, and the filtrate was concentrated under reduced pressure. Purification by flash chromatography (SiO2, 100-200 mesh; 25-30% EtOAc in petroleum ether) afforded the title compound as an off-white solid (1.5 g, 56%): mp 158-160° C.; 1H NMR (400 MHz, CDCl3) δ 8.40 (m, 1H), 7.89 (m, 2H), 7.74 (m, 2H), 7.64 (m, 2H), 7.58 (m, 2H), 7.46 (s, 2H), 7.36 (m, 2H), 6.31 (m, 1H), 5.30 (s, 2H), 4.21 (m, 1H); ESIMS m/z 572.08 ([M−H]−).
