An atom-economical metal-free photoredox three-component coupling of thiols with readily available alkynes and α-vinylsulfide has been developed. The reaction uses the easy-to-handle EosinY/DBU photocatalytic system, resulting in a one-potsynthesis of C−S and C−C bonds. The reaction mechanism was investigated by combining mass spectrometry, EPR spectroscopy, isotope labeling, cyclic voltammetry, Stern–Volmer

coupling of thiols with readily available alkynes and alkenes has been developed. The reaction mechanism was evaluated by combining ESI-HRMS, EPR spectroscopy, isotope labeling and control experiments. The applicability of the reversible radicaladdition approach for intermolecular reactions and the key role of π–π stacking interactions in stereoselectivity control have been shown by DFT studies.
