실험 절차

0.112 g (0.5 millimol) of palladium acetate, 10.05 g (50 millimols) of 4-chlorocinnamyl chloride, 6.5 g (62.5 millimols) of styrene and 9.27 g (50 millimols) of tri-n-butylamine in 50 ml of p-xylene are stirred for 23/4 hours at 120° C. The crude product is chromatographed on silica gel in methylene chloride and is recrystallised from n-hexane. 0.5 g (4% of theory) of the above compound are obtained in the form of white crystals of melting point 161.2° C.
