Abstrakt: An efficient transition-metal free iodine-mediated tuneable disulfonylation and sulfinylsulfonylation of alkynes with sodium arylsulfinates under visible light irradiation has been developed. This photochemical protocol offers broad substrate scope of 1,2-bissulfonylethenes with high functional group tolerance and good yields under mild reaction conditions. In addition, it was found that β-sulfinyl alkenylsulfones can be obtained in the absence of base. It is proposed that the reactions proceed via sulfonyl and sulfinyl radicals.
