Title Thiolfree route to diaryl sulfides by Cu catalyzed coupling of sodium thiosulfate with aryl halides Type Article Keywords Not Record Abstract A method for the synthesis of diaryl sulfides from aryl halides in polyethylene glycol was reported. Inodorous Na2S2O3·5H2O, which is readily available as a stable salt, is an effective source of sulfur in the presence of CuI as catalyst.
