Iron-Promoted Synthesis of Substituted 1-Halo-1,4-pentadienes by Reaction of 1,3-Diarylpropenes with Ethynylbenzenes via sp(3) C-H Bond Activation

[摘要]：An iron-promoted sp(3) 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.
