Versuchsvorschrift

4-Bromobenzaldehyde (370 mg, 2 mmol), phenylacetylene (306 mg, 3 mmol) and tetrakistriphenylphosphine palladium (45 mg) were dissolved in triethylamine (4 ml), and the obtained solution was stirred at 80° C. in argon atmosphere for 24 hours. The solvent was evaporated, and the product was purified by the silica gel column chromatography to obtain 4-(2-phenylethynyl)benzaldehyde (yield: 258 mg, 63%)
