実験手順
A mixture of 3-chloro-4-iodobenzotrifluoride (5.00 g), copper(I) iodide (62.1 mg), triphenylphosphine (214 mg), tris(dibenzylideneacetone)dipalladium(0) chloroform adduct (337 mg), propargyl alcohol (1.06 ml), diisopropylethylamine (11.4 ml) and tetrahydrofuran (100 ml) was stirred at room temperature for 17 hr. The reaction mixture was added to brine, and the mixture was extracted with ethyl acetate, washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=99:1-80:20) to give the object product (3.05 g) as a brown solid.
