反应条件: temp:130.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a two-necked RB flask under nitrogen was added 1.39 g (3.3 mmol) of 3,3′-diiodo-2,2′-bithiophene, 222 mg (0.33 mmol) of Pd(OAc)2, 2.5 g (10 mmol) of 9-octadecyne, tributyl amine 1.85 g (10 mmol), and 10 mL of anhydrous DMF. The mixture was heated at 130° C. for 4 hours. After cooling down to room temperature, 50 mL of ether ethyl was. The organic phase was washed with water several times, dried by MgSO4, concentrated under reduced pressure. The residue was further purified by flash chromatography on silica gel (hexane as eluent) to afford the pure product as a colorless liquid (1.16 g, yield: 85%). 1H NMR (300 MHz, CDCl3) δ 7.46 (d, 2H, J=5.43 Hz), 7.37 (d, 2H, J=5.42 Hz), 3.01 (t, 4H, J=7.89 Hz), 1.68 (m, 4H), 1.51 (m, 4H), 1.30 (m, 16H), 0.89 (t, 6H, J=6.7 Hz). 13C NMR (400 MHz, CDCl3) δ 137.47, 131.58, 131.32, 123.55, 123.38, 31.87, 31.52, 30.43, 30.16, 29.48, 29.27, 22.63, 14.04. MS: m/z=414.7 [M]+ (Calcd.: 414.7). After cooling down to room temperature The organic phase was washed with water several times dried by MgSO4 concentrated under reduced pressure The residue was further purified by flash chromatography on silica gel (hexane as eluent)
