and stereoselective transformation of commercially available 4-bromo-3,3,4,4-tetrafluoro-1-butene into multisubstituted alkenes having a tetrafluoroethylene fragment through Heck reactions and/or Suzuki–Miyaura cross-coupling reactions was established. Thus, the obtained alkenes underwent a smooth reductive coupling reaction with aldehydes under the influence of MeLi/LiBr-free, affording structurally

丁烯向具有
四氟乙烯片段的多取代烯烃的高度区域选择性和立体选择性转化。因此,所获得的烯烃在无MeLi / LiBr的影响下与醛进行了平滑的还原偶联反应,从而提供了结构上前所未有的
