---|---|---|
93% | Stage #1: With bis-triphenylphosphine-palladium(II) chloride; copper(l) iodide; triethylamine In acetonitrile at 20℃; for 0.5 h; Inert atmosphere Stage #2: at 20℃; Inert atmosphere |
General procedure: 2-iodoaniline (500.2 mg, 2.28 mmol, 1.0 equiv) was dissolved in Et3N (4.5 mL). The resulting solution was added with PdCl2(PPh3)2 (32.1 mg, 0.046 mol, 0.02 equiv) and CuI (17.4 mg, 0.091mmol, 0.04 equiv). The orange-yellow solution was degassed by bubbling with a stream of argon into the solution at room temperature for 30 min. After degassing, phenylacetylene (0.30 mL,279.0 mg, 2.73 mmol, 1.2 equiv) was added as a neat liquid into the solution via syringe. The resulting dark brown solution was allowed to stir at room temperature under argon atmosphere overnight. The reaction was quenched by addition of sat. aq. NH4Cl. The separated aqueousphase was extracted with EtOAc (3x times). The combined organic phases were washed with sat. aq. NaCl, dried over anh. Na2SO4, filtered and concentrated to a crude product. The crudeproduct was purified by SiO2 column chromatography eluting with 0-10percent EtOAc-hexane to give 398.2 mg (90percent) of 2-(phenylethynyl)aniline as an orange solid. |
75% | With sodium hydroxide In toluene at 130℃; for 72 h; | General procedure: To a stirred solution of the corresponding 2-iodoaniline (6, 1 mmol) in toluene (3 mL) under argon atmosphere were added Pd/CuO-Fe3O4 (50 mg), NaOH (400 mg, 10 mmol), and the corresponding alkyne (2, 1.5 mmol). The resulting mixture was stirred at 130 °C until the end of reaction (see Table 6). The catalyst was removed by a magnet and the resulting mixture was quenched with water and extracted with EtOAc. The organic phases were dried over MgSO4, followed by evaporation under reduced pressure to remove the solvent. The product was purified by chromatography on silica gel (hexane/ethyl acetate) to give the corresponding compounds 7. Yields are included in Table 6. Then, to a stirred solution of 7 (1 mmol) in toluene (4 mL) was added ZnBr2 (225 mg, 1 mmol). The resulting mixture was stirred at 130 °C during 24 h. The mixture was quenched with water and extracted with EtOAc. The organic phases were dried over MgSO4, followed by evaporation under reduced pressure to give the pure products 8 in quantitative yields. Physical and spectroscopic data for compounds 7 and 8, as well as literature for known compounds, follow. |
