実験手順

The procedure described in Example 1 is followed, except that 8.43 g (0.05 mol) of 4-formylbenzoyl chloride, 6.5 g (0.0625 mol) of styrene, 17.5 g (0.05 mol) of tri-n-octylamine, 100 ml of dioxane as the solvent and 0.287 g (0.0005 mol) of bis-(dibenzylideneacetone)-palladium(O) are used. After a reaction time of 2 hours at 120° C., 5.8 g (0.0279 mol) of 4-formylstilbene, corresponding to a yield of 56% of theory, are obtained as yellowish crystals; melting point 112°-113° C.
