Procedure

3 g (8.8 mmol) of 3-(1-adamantyl)-4-methoxyethoxymethoxyphenylacetylene, 1.8 g (9.7 mmol) of 4-bromobenzaldehyde and 50 ml of triethylamine were introduced into a three-necked flask. The reaction mixture was degassed with nitrogen for 15 min, 160 mg (1.7 mmol) of palladium(II) acetate and 350 mg (1.3 mmol) of triphenylphosphine were added and stirring was carried out at room temperature for twelve hours. The reaction mixture was evaporated to dryness, the residue was taken up in water and ethyl ether and the organic phase was separated by settling, dried over magnesium sulfate and evaporated.
