Abstract: Cis, cis-1, 4-dibromo-1,2,3,4-tetraphenyl-1,3-butadiene is obtained from the reaction of 1, 4-dilitho-l,2,3,4-tctraphenyl-l,3-buladicnc with carbon tetrabro-mide. The molecular structure of the product is determined by the results of elementary analysis, MS, 1R, NMR and single crystal X-ray diffraction. That, the molecular structure of the product is not coplanar, is thought to be caused by the steric hindrance between the substituents.
