Copper-catalyzed sulfonylation of alkenes with CHSSONa.

A successful methodology for the copper-catalyzed dehydrogenated methylsulfonylation of alkenes utilizing CHSSONa in conjunction with hypervalent iodine reagents was successfully established. This method offers a practical avenue to obtain allyl methyl sulfones and alkenyl methyl sulfones by forming C-S bonds. Using the C-H bond oxidation sulfonylation strategy with alkenes and Bunte salts, we successfully synthesized a total of twenty two compounds, including four examples of deuterium-substituted molecules, and demonstrated one example of a scale-up reaction.
