α,β-Unsaturated phosphine sulfides may exhibit different reactivity from α,β-unsaturated phosphine oxides toward nucleophilic addition and thus may find new applications in copper(I)-catalyzed asymmetric reactions. Herein, various α,β-unsaturated phosphine sulfides were prepared in moderate to excellent yields from the parent α,β-unsaturated phosphine oxides with Lawesson’s reagent. The reaction enjoys
α,β-不饱和膦硫化物可能表现出与α,β-不饱和氧化膦不同的亲核加成反应性,因此可能在铜(I)催化的不对称反应中发现新的应用。在此,用Lawesson试剂以母体α,β-不饱和氧化膦的产率以中等至优异的产率制备了各种α,β-不饱和膦的硫化物。该反应具有广泛的底物范围并且可以耐受多种官能团。
