Sodium Carbonate → 3-(1-Naphthyl)-1-bromobenzene

Participants

Reaction Steps

Under an argon gas atmosphere, 200.0 g (1.163 mol) of 1-naphthaleneboronic acid, 329.0 g (1.163 mol) of 3-bromoiodobenzene, 26.9 g (23.3 mmol) of tetrakis(triphenylphosphine)palladium(0), 3.7 L of toluene and 1.74 L of aqueous solution of 2M sodium carbonate were added together, and stirred while being refluxed for 24 hours. After the reaction was over, the mixture experienced filtration, through which aqueous phase thereof was eliminated. After organic phase thereof was washed by water and dried with magnesium sulfate, the toluene was distilled away under reduced pressure. Residue thereof was refined by silica-gel column chromatography, such that 250 g of 1-(3-bromophenyl)naphthalene was obtained at an yield of 76%.
