A highly regioselective and catalyst-free sulfonation of allylic alcohols with sulfinyl amides has been realized. Such a mix-and-go procedure provides a convenient approach to synthetically various allylic sulfones under mild reaction conditions. Furthermore, this novel reaction shows ample substrate scope and outstanding functional group tolerance and could also be scaled-up. Meanwhile, it is the
sulfinate salt, allylic sulfones were synthesized by palladium‐catalyzed cross‐coupling of aryl iodide with N‐tosylhydrazone. In this transformation, not only the diazo compound but also the sulfinate salt, which were both generated in situ from base‐mediated decomposition of the N‐tosylhydrazone, was used as nucleophilic partner.
