  摘要：

  在碘化亚铜的存在下，取代的四氟苯基卤化物与1-炔烃的钯催化偶联反应在温和条件下以良好或优异的收率得到相应的氟芳基炔烃。4-取代的（甲氧基，N，N-二甲基氨基，吗啉代）四氟苯基碘和溴离子均能很好地起作用，并且在反应条件下，炔烃部分中的烷基，三甲基甲硅烷基，苯基，羟基和醚官能团是可容忍的。该方法提供了取代的氟化芳基炔烃的实用合成。

  In the presence of cuprous iodide, the palladium-catalyzed coupling reaction of 4-substituted tetrafluorophenyl iodides 1 with terminal alkynes proceeds readily in diisopropylamine or triethylamine to afford the corresponding fluorinated phenylalkynes in excellent yields under mild conditions. A variety of substituents on F-benzenes such as methoxy, dimethylamino, hydro, acyl, piperidino, and morpholino do not interfere with the coupling reaction. The reaction works well with 1-alkynes containing functional groups, including alkyl, alkenyl, phenyl, vinyl ether, alkoxy, phenoxy, hydroxy, amino, trimethylsilyl, and cyano, to give the corresponding (fluorophenyl)alkynes. With dialkynes, 2 equiv of the fluorinated phenyl iodide give bis(fluorophenyl)dialkynes in good yields. When 1,4-dibromotetrafluorobenzene reacts with an excess of alkyne in diisopropylamine, the bis-alkynylated tetrafluorobenzenes are obtained in good yields. However, in triethylamine the reaction gives a mixture of mono- and bis-alkynylated products. This method provides a practical approach to fluorinated phenyl functionalized alkynes.
