A 10 ml Schlenk tube equipped with a magnetic stirrer is charged with 218 mg (0.8 mmol) 3,5-diacetoxybromobenzene, 136 mg (0.84 mmol) 4-acetoxystyrene, 187 mg potassium carbonate (0.9 mmol) and 0.22 mg (0.1 mol %) of the acetophenon-oxim derived palladium catalyst CAS No. 32679-19-9 as used in Example 9. The tube was evacuated and flushed with argon three times and 1 ml de-aerated DMF was added under inert conditions. The reaction was carried out under stirring for 15 hours at 150° C. Work-up was conducted following the procedure of Example 4 and to give (E)-3,4′,5-triacetoxystilbene.
