Cu(OTf)2-Catalyzed efficient sulfonylation of vinyl azides with sodium sulfinates

Abstract
A simple oxidative cross-coupling reaction between vinyl azides and sodium sulfinates was developed. This reaction uses commercial arylsulfinates that are more efficient, cheaper, and more stable as sulfonylation reagents, for efficiently, cheaply, and environmentally friendly synthesis of β-keto sulfones. And the reaction has the advantages of simple operation, high efficiency, good yield, and also has a wide range of functional group tolerance. Graphical Abstract
