pentafluoropropen‐1‐yl sulfone or sulfoxide, which are easily prepared from commercially available 1,2‐dibromofluoroalkanes, with various organocuprates affords substitution or β‐reduction products in good to excellent yields through an addition–elimination reaction sequence.
三氟乙烯或五氟丙烯-1-基砜或亚砜可以很容易地从市售的1,2-二溴氟代烷烃中制备,并用各种有机铜酸盐处理,通过加成-消除反应顺序,可以得到取代或β-还原产物,收率良好,收率极好。
