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

Participants

Reaction Steps

Under an argon gas atmosphere, 200.0 g (1.163 mol) of 1-naphthalene boronic 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 2M sodium carbonate solution were mixed, and stirred for 24 hours while being refluxed. After the reaction in the mixture was over, the mixture experienced filtration, through which aqueous phase thereof was eliminated. After organic phase thereof was cleansed by water and dried with magnesium sulfate, 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 with an yield of 76%.
