Abstract
Copper-catalyzed cross-coupling reactions of phenolic esters such as acetates, tosylates, and triflates with arylboronic acids or triphenyltin chlorides as the coupling partners in the presence of sulfur and a base provide unsymmetrical diaryl sulfides. In addition, NaOtBu promotes a synthesis of symmetrical diaryl sulfides from phenolic compounds in the presence of sulfur.
