The general catalytic synthesis of aryl and vinyl thioethers from readily available halides remains a challenge. Herein we report a unified method for the thiolation of aryl and vinyl iodides with dialkyl disulfides using visible light photoredox catalysis. A range of thioether products bearing diverse functional groups can be accessed in high yield and with excellent chemoselectivity. We demonstrate

The reaction of dimethylsulfide ditriflate with alkenes leads to the corresponding sulfonium salts. Dependence of the reaction course on the substrate structure is discussed. In the reactions with norbornene and norbornadiene the sulfonium salts with nortricyclene skeleton were obtained. The configurations of the two isomeric disubstituted nortricyclanes 21a,b were determined by NMR.
