An iron-promoted sp3 C−H bond activation and C−C bond formation reaction between 1,3-diarylpropenes and ethynylbenzenes was realized with BQ (benzoquinone) as an oxidant. The reaction afforded 1-halo-1,4-pentadiene derivatives in moderate to good yields under mild conditions.
以BQ(苯醌)为氧化剂,实现了铁促进的sp 3 C-H键活化和1,3-二芳基丙烯与乙炔基苯之间的CC键形成反应。该反应在温和条件下以中等至良好的产率提供了1-卤代-1,4-戊二烯衍生物。
