A zinc-mediated cross-electrophile coupling of benzyl sulfonium salts with thiosulfonates via C-S bond cleavage was achieved. The reductive thiolation proceeded well under transition metal-free conditions to afford the desired sulfides in good yields, exhibiting both broad substrate scope and functionality tolerance. In addition, reaction could be applied use selenosulfonate as an effective selenylation agent subjected scale-up synthesis.
