摘要：
The sulfur-mediated difunctionalization of alkynes is reported to give alpha-acetoxy ketones in a one-pot operation under mild conditions with 19-92% yield. By using wet potassium acetate as both the aqueous base and nucleophilic reagent, both terminal alkynes and internal alkynes could be converted into the alpha-acetoxy ketone products.
