2-(3,3-Dimethylbut-1-ynyl)benzofuran was synthesized by the reaction of 2-ethynylphenol and (E)-1,2-diiodo-3,3-dimethylbut-1-ene in the presence of palladium(Ⅱ)acetate and copper(Ⅰ)iodide as catalyst via an one-pot reaction in triethylamine-tetrahydrofuran media.The mixture was stirred under argon atmosphere at r.t.for 15 h,and then at 100℃ for 13 h to afford.the target compound.The reaction was readily performed with good yield under mild conditions and convenient operations.The structure of the product was characterized by NMR and MS methods.
