A copper-catalyzed thiolation of terminal aromatic alkynes by disulfur transfer to access alkynyl disulfides was developed. Different types of products were afforded due to the steric hindrance of dithiolsulfonates. Some important compounds, such as fully substituted triazoles and pyrene-gemcitabine conjugate were prepared by this new approach.

铜催化末端芳族炔烃的硫醇化反应,获得炔基二硫化物

开发了铜催化的末端芳族炔烃通过二硫转移而获得的炔基二硫化物的硫醇化反应。由于二硫代磺酸盐的空间位阻,提供了不同类型的产品。通过这种新方法可以制备一些重要的化合物,例如完全取代的三唑和s-吉西他滨偶联物。
