To a two-necked flask was charged with iodobenzene (1.09 mL, 9.80 mmol, 1.0 equiv.), ethynylbenzene (1.18 mL, 10.7 mmol, 1.1 equiv.), bis(triphenylphosphine)palladium(II) dichloride (137 mg, 0.195 mmol 2.0 mol%), copper(I) iodide (40 mg, 0.210 mmol, 2.1 mol%), tetrahydrofuran anhydrous (40 mL), triethylamine (1.90 mL, 14.7 mmol, 1.5 equiv.) under nitrogen atmosphere. The mixture was stirred at room temperature for 1.5 h. The reaction mixture was quenched with water (20 mL). The organic layer was washed with brine (10 mL), dried over Na2SO4 and then concentrated under reduce pressure. The crude was purified by column chromatography on silica gel (hexane) to afford diphenylacetylene as a white powder (1.70 g, 97 %).
The reaction mixture was monitored by GC.
1H NMR (400 MHz, CDCl3); δ 7.51-7.54 (m, 4H), 7.31-7.35 (m, 6H).
13C NMR (101 MHz, CDCl3); δ 131.6, 128.3, 128.2, 123.2, 89.3.
