The preparation of 4,4'-Divinylbiphenyl is as follows: Reaction flask (10 mL) equipped with stirring bar was charged with 4-vinylphenylboronic acid (135mg, 0.91 mmol), ethanol (96%) (2 mL), [{Pd(μ-OH)Cl(IPr)}2] (510-4 g, 4.55 × 10-7 mol). Reactionmixture was stirred at 22 C for 6 h. After completion of the reaction solvent was evaporated, theresidue was dissolved in hexane (5 mL) and extracted with water (2 × 2 mL). The organic layer wasdried over magnesium sulphate, and hexane was evaporated under reduced pressure. 176 mg of 4,4'-divinylbiphenyl was obtained as a white solid. Yield = 93%.
