Sodium Carbonate → Dimethyl 2-phenylterephthalate

Participants

Reaction Steps

A mixture of dimethyl 2-iodoterephthalate (22.8 g, 71.4 mmol) and tetrakis(triphenylphosphine)palladium(0) (4.14 g, 3.38 mmol) in toluene (120 mL) was stirred for 10 minutes. Aqueous sodium carbonate (2 M, 160 mL) and a solution in methanol (40 mL) of phenylboronic acid (10.4 g, 85.3 mmol) were then added and the reaction mixture was stirred at reflux for 15 hours. The reaction mixture was cooled to ambient temperature and extracted with ether. The organic phase was washed with water (2×) and brine, dried, and concentrated in vacuo to give dimethyl 2-phenylterephthalate as a dark brown oil (18.4 g) which was used without further purification.
