반응 단계
A 10 ml Schlenk tube equipped with magnetic stirrer was charged with 59 mg (0.7 mmol) of 4-acetoxychlorobenzene, 100 mg (0.84 mmol, 1.2 eq) of 3,5-diacetoxystyrene, 125 mg of cesium carbonate (0.38 mmol, 1.1 eq), 5 μl of P(t-Bu)3 (0.02 mmol, 6 mol %) and 5.57 mg (0.01 mmol, 1.5 mol %) of tris(dibenzylideneacetone)-dipalladium chloroform complex. The tube was evacuated and flushed with argon three times and 1 ml de-aerated dioxane was added under inert conditions. The reaction was carried out under stirring for 19 hours at 120° C. Work-up was conducted following the procedure of Example 5 and gave (E)-3,4′,5-triacetoxystilbene.
