Versuchsvorschrift

N-Allylphthalimide (13.9 g, 74.3 mmol), 1-fluoro-4-iodobenzene (15.0 g, 67.6 mmol) triethylamine (15.0 g, 148 mmol) and Pd(OAc)2 (152 mg) were heated at 104° in a glass bomb with shaking for 18 h under an inert atmosphere. The reaction mixture was dissolved in hot acetonitrile. The catalyst was removed by filtration and the filtrate cooled to 0°. The precipitated white solid product was filtered off and dried under vacuum. This title material (12.55 g) was used without further purification.
