Coupling of arylboronic acids with potassium ethyl xanthogenate enables a simple and environmentally benign one-pot synthesis of diaryl thioethers through a double arylation process. The aryl thiols were generated in situ, and the reactions proceeded smoothly to give the corresponding products in good to excellent yields under very mild conditions.
