Versuchsvorschrift

15.3 g (43.6 mmol) of 1-iodo-4-bromonaphthalene and 7.25 g (5.3 mmol) of 4-n-propylphenylacetylene are initially introduced in 200 ml of NEt3, 170 mg (0.9 mmol) of copper(I) iodide and 600 mg (0.9 mmol) of bis-(triphenylphosphine)palladium(II) chloride are added, and the mixture is refluxed for 30 minutes. The batch is cooled, water and heptane are added, and the phases are separated. The organic phase is washed with saturated sodium chloride solution, dried over sodium sulfate, filtered and evaporated in a rotary evaporator. The residue is purified by column chromatography (SiO2, heptane), and the further purification is carried out by recrystallisation from isopropanol.
