β-Chloroalkyl Sulfides from Me2S/SO2Cl2/Me2SO and Alkenes
摘要:
A novel method to prepare beta-chloroalkyl sulfides from alkenes and Me2S-SO2Cl2-Me2SO is described, methanesulfenyl chloride being suggested as intermediate.

We report a novel method for the chlorothiolation of alkenesusing HCl and sulfoxides to achieve the 1,2-difunctionalization of unactivated alkenes. The combination of our new HCl reagent (HCl/DMPU) with sulfoxides forms a unique chlorothiolation system. Both terminal and internal alkenes are suitable substrates. This method works at gram scale and is applicable in further synthetic elaborations.
