been developed for the synthesis of symmetric and unsymmetric diarylsulfides at room temperature and in air. This methodology is reliable and offers a mild and easy to operate process for the synthesis of arylthioethers, which are essential compounds with applications in the pharmaceutical and agricultural industries. This method avoids the use of expensive transitionmetals, such as Pd, Ir or Rh,
A Cu/hydrazone catalysis has been applied in the oxidative coupling of arylboronic acids and aromatic thiols for the synthesis of asymmetric diaryl sulfides. The reaction features mild conditions and readily available hydrazone ligand. It works for a wide range of arylboronic acids and thiols with good to excellent yields, exhibiting great potential of such hydrazone ligands in organic synthesis.
Selective single arylsulfanylation reactions of aryl diiodides with aryl or hetaryl thiols to give a broad array of iodine-functionalized sulfides were developed. Further elaboration of the iodine-containing products to provide a variety of aryl and hetaryl sulfides through coupling reactions was also demonstrated.
