摘要

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 ...
