An efficient copper(I)/proline sodium salt‐catalyzed alkyl‐ and arylsulfenylation of C(sp2)–X 3,4‐dihalo‐2(5H)‐furanone compounds with sulfoxides is described. For inexpensive C(sp2)–Cl compounds, there is also a satisfactory reactivity with the moderate yields. This transformation provides a novel approach for the utilization of sulfoxides (not only DMSO) as sulfur source at mild temperatures without
描述了一种有效的铜(I)/脯氨酸钠盐催化的亚砜与C(sp 2)–X 3,4-二卤代-2-(5 H)-呋喃酮化合物的烷基和芳基亚磺酰基化反应。对于廉价的C(sp 2)–Cl化合物,中等收率也具有令人满意的反应性。这种转变提供了一种在温和的温度下利用亚砜(不仅是DMSO)作为硫源的新颖方法,而无需厌氧气氛。更重要的是,亚砜和脯氨酸钠盐均可在该反应中起双重作用。
