A novel and efficient synthesis of sulfones was developed via a silver-promoted decarboxylative sulfonylation reaction between aromatic carboxylic acids and sodiumsulfinates for the first time. The approach features operational simplicity and good functional group compatibility and uses readily available starting materials. Furthermore, mechanistic studies reveal that the decarboxylative sulfonylation
Here we report the utilization of commercially available p-toluenesulfonhydrazide as a new nucleophilic reagent in displacement reactions with suitable halides for an improved, general synthesis of sulfones. Good results are obtained with primary, secondary, allylic, benzylic, and aromatic halides activated by withdrawing groups.
