sodium dithionite and thiourea dioxide have been used as the source of sulfonyl group in the synthesis of sulfones and sulfonamides recently. Compared with other methods for the sulfonylation reactions, the strategies using sodium dithionite or thiourea dioxide provide an alternative and complementary route to diverse sulfonyl compounds. During the reaction process, sulfurdioxideanionradical is the

The commercially available and cheap sodium dithionite is used as the source of sulfonyl group for the synthesis of sulfones and sulfonamides from (hetero)aryl iodides under catalyst‐free conditions. During the reaction process, sodiumsulfinates generated in situ are the key intermediate, which can be further converted into diverse sulfones and sulfonamides. This transformation proceeds through a
