Silver‐Catalyzed Denitrative Sulfonylation of β‐Nitrostyrenes: A Convenient Approach to (E)‐Vinyl Sulfones

Abstract The first utilization of β‐nitrostyrenes (readily available by the Henry reaction) for a highly stereoselective, convenient, and catalytic synthesis of ( E )‐vinyl sulfones at room temperature was investigated. The protocol involves efficient silver‐catalyzed denitrative radical cross‐coupling of β‐nitrostyrenes and sodium sulfinates by using potassium persulfate as an additive to complete the catalytic cycle.
