実験手順

5.74 g (21.7 mmol) of 1-iodo-4-methoxymethoxybenzene, 100 ml or triethylamine and a mixture of 1.53 g (2.18 mmol) of dichloro-bis(triphenylphosphine)palladium and 831 mg (4.37 mmol) of copper iodide are introduced into a three-necked flask. 6.14 ml (43.5 mmol) of trimethylsilylacetylene are then added and the medium is stirred for 48 h at room temperature. It is then poured into a water/ethyl acetate mixture. The organic phase is washed twice with water and, after separation of the phases by settling, it is washed with magnesium sulphate and concentrated.
