반응 단계
0.112 mg (0.5 millimols) of palladium acetate, 10.97 g (50 millimols) of 4-bromobenzoyl chloride, 10.17 g (50 millimols) of 4-bromostyrene and 6.76 g (50 millimols) of N-benzyldimethylamine in 100 m of o-xylene are stirred for 1 hour at 130° C. After having filtered off the amine salt which has precipitated, the filtrate is concentrated and the crude product is recrystallised twice from toluene. 7.8 g (46% of theory) of 4,4'-dibromostilbene are obtained in the form of white flakes; melting point 213.3° C.
