Reaction Steps
The procedure described in Example 1 is followed, except that 23.07 g (0.1 mol) of 3,4,5-trimethoxybenzoyl chloride, 13.02 g (0.125 mol) of styrene, 12.93 g (0.125 mol) of ethyl diisopropylamine and 0.3046 g (0.001 mol) of bis-(acetylacetonato)-palladium(II) are used. After a reaction time of 3 hours at 130° C., in 50 ml of cyclohexanone as the solvent, 4.7 g (0.0175 mol) of 3,4,5-trimethoxystilbene, corresponding to a yield of 17.5% of theory, are obtained in the form of white needles; melting point 108° C.
