The procedure described in Example 1 is followed, except that 17.5 g (0.1 mol) of 4-chlorobenzoyl chloride, 13.02 g (0.125 mol) of styrene, 35.37 g (0.1 mol) of tri-2-ethylhexylamine and 0.1773 g (0.01 mol) of palladium chloride are used. After a reaction time of 4 hours at 120° C., 9.3 g (0.0433 mol) of 4-chlorostilbene, corresponding to a yield of 43.3% of theory, are obtained in the form of white flakes; melting point 129°-130° C.
