has not been applied in organic synthesis except the formation of disulfones by self-dimerization of sulfonyl radicals. In this article, they were introduced as new sulfonylating reagents and their combinations with NIS and Et3N were established as excellent iodosulfonylating reagents for alkenes. Finally, a highly efficient method for the synthesis of (E)-vinyl sulfones was developed by mixing an alkene
