Toluene → 3'-(Trifluoromethoxy)[1,1'-biphenyl]-4-carbaldehyde

Participants

Reaction Steps

A mixture of toluene (35 mL) and water (5 mL) was degassed with nitrogen for 30 minutes. A mixture of sodium carbonate (1.9 g, 18.09 mmol), 4-bromobenzaldehyde (0.7 g, 3.72 mmol), 3-trifluoromethoxyphenylboronic acid (2.86 g, 4.78 mmol) and tetrakis triphenyl phosphene palladium(0) (0.9 g, 0.75 mmol) was added to the above degassed water/toluene mixture. The reaction mixture was refluxed overnight. After the reaction is completed it was cooled to room temperature and extracted with ethyl acetate. The combined organic layers were dried over sodium sulphate and concentrated. The resulting residue was purified by column chromatography using 5% ethyl acetate in hexane to obtain the title compound (0.8 g, 80%).
