A method for base-promoted synthesis of 1,2-bis(arylthio)arenes is reported. Arynes generated from aryl triflates, sulfamates, and halides react with diaryl disulfides to afford 1,2-bis-arylthioarenes. Unsymmetrical diaryl disulfides form products in acceptable yields and regioselectivities. Use of a new amide base in aryne generation allows for decreased amount of byproduct formation.
