Alkyne-based, highly stereo- and regioselective synthesis of stereodefined functionalized vinyl tellurides

Research on bifunctionalized vinyl tellurides paves the way for the stereo- and regioselective synthesis of vinyltellurides containing sulfonyl, phosphonyl, and iodo groups from stereo- and regiodefined addition of tellurides with alkynes. Data show that arylsulfinate serves as a sulfonyl radical precursor, while diaryl ditellurides as radical acceptors.
