Rhodium(II)/phosphine-cocatalyzed bis-sulfuration of α-diazocarbonyl compounds using thiosulfonates as the sulfenylating agent, which provided two sulfur-containing moieties, was developed via simultaneous inter- and intra-molecular C–S bond formation. This novel protocol provides a rapid synthetic route to dithioketal derivatives in moderate to good yields in an atom-economic process. The transformation
铑(Ⅱ)/膦用硫代磺酸盐作为亚磺酰化剂对α-重氮羰基化合物的双硫化双硫化,通过同时形成分子间和分子内CS键而形成,提供了两个含硫部分。该新方案为原子经济过程中中等至良好的产率提供了快速合成二硫代缩酮衍生物的途径。有人建议通过膦叶立德的形成,然后进行S(O 2)-S键的裂解和重排来进行转化。
