Cadiot and W. Chodkiewicz, Chemistry of Acetylenes, H. G. Viehe, ed., Marcel Dekker, New York (1969)). More specifically, 20 ml of dried THF was added to 341 mg (14 mmol) of magnesium and thereto, a 10 ml THF solution containing 2.70 g (15 mmol) of 4-bromostyrene was added dropwise to prepare a Grignard reagent. To the resulting solution, a 10 ml THF solution containing 2.50 g (11 mmol) of chlorodiphenylphosphine was added dropwise and stirred at room temperature of 1.5 hours. After removing the solvent by distillation under reduced pressure, the residue was purified by silica gel column chromatography and recrystallized from a hexane solution to obtain 2.30 g (8.3 mmol) of (4-vinylphenyl)diphenylphosphine Compound (B).
