Recent advancements in C–S bond formation via electron donor-acceptor (EDA) photoactivation have been highlighted. EDA complexes, which composed of electron donors and acceptors, facilitate C–S bond construction under mild conditions through single-electron transfer events upon visible light irradiation. This review highlights the utilization of various sulfur-containing substrates, including DABSO, sulfonic acids, sodium sulfinates, sulfonyl chlorides, and thiophenols, in EDA-promoted sulfonylation and thiolation reactions, covering the works published since 2017 to date. These reactions offer novel, environmentally friendly pathways for the synthesis of sulfur-containing compounds.
