Example 71, metal content 0.1%) are suspended in 20 ml of DMF. After 2 mmol of iodobenzene, 2 mmol of styrene, and 4 mmol of tetrabutylammonium acetate have been added, heating at 60° C. is performed with shaking. After 12 h, 288 mg of stilbene can be isolated from the reaction solution. This corresponds to an 80% yield.
