2-（3,3-Dimethylbut-1-yny1）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 13h to afford, the target compound. The reaction was readily performed with good yield under mild conditions and convenient operations. The structure of th...
